I just bought a 257 and getting ready to work up a load for KY whitetails. I need a bullet that will be good from up close out to 250yds or so. This is my first rodeo with the quarter bore. Im thinkin 100g partition or BT but I have a couple of flavors of 117g bullets. What are ya'll shootin in em and what are the results?

There's a lot of good 25 caliber bullets available that would meet your requirements. Either the 100 or 120 grain partitions, the 100-120 grain Speer, Hornady or Sierra offerings, even the good old Hornady 117 round nose would serve you well in the role you describe.

If I was only ever going to hunt deer the rest of my life and could have only one rifle with which to hunt them, I'd chose the 257 Roberts and a 100-120 grain bullet. I'd just chose the one my rifle shot the best.

I have a 250AI (which is pretty close to a roberts) and have pretty good luck with 100 BT's I would have to look it up to be sure, but RL-15 and 3100 fps seems to ring a bell.

The 100g BT seems to hold together and exit. I mostly try for the high shoulder shot and a DRT.

I mostly shoot 100 grain Partitions and 110 grain ABs at whitetails from my 257s and 257AIs. I am going to give the 80 grain Barnes TTSX a try as a means by which to bump up the velocity to 3300+/- fps. Folks that use them claim that they shoot flat, penetrate deep, and kill quickly from any angle.

Cool!

In very older days I used 47 grains of surplus 4831 with any ol' cup and core 100 grain bullet. Deer die.

More recently I've used the 120 grain partition, federal magnum primers, and 43 grains of H414. The last deer I shot with it was more or less head on. I shot it right under the chin, broke it's neck, the bullet exited out the back of the neck, went through a few inches of air, went back into the shoulder, and went right down the rib cage tumbling but cut every rib off. Total penetration was about 20 inches of bone and meat plus 3 layers of hide.

Of the .257s I've shot, there has been either a really clear like or really clear dislike for 100 grain bullets. If 100s work, awsome. If not, try 120.

Don't overlook the hornady 117 grain BTSP, 110 grain accubond, and 115 grain ballistic tip.

I've only used the 100 Hornady on deer, but every one I've pulled the trigger on have gone into my freezer with one shot apiece. Son-in-Law got one with the 115 Partition without drama. Cheezy got a couple with the 100 TSX and I've got some 100 BTs to try out some time. Doesn't seem to be any secrets, just put a decent bullet where it belongs.

My son uses the 117 grain spire points.

Ale81. I have used the 257 in Kentucky for several years and think you will be very pleased. I'm sure 100 gr bullets will be fine but you might as well use a 243. I have had excellent luck with both 120 gr corelokt and 117 gr. interlocks using H414 and pushing around 2800 fps. Furthest I've had a deer go is about 35 yds. Never caught a bullet.

Gotta love that Clark Co stump water.

That 100 grain Partition you mentioned should work very well.

I have twin Bob's that shoot the 115 grain Partition better than most bullets. There are no what if's or second guessing with that bullet.

43-44 grains H 4350, 2845 fps to 2860 fps.

I have used 100 and 117 Hornady interlock and the 100 ballistic tip and partition, all worked great. The 100 Hornady is probably my favorite but truth be told you would have a hard time finding any halfway appropriate bullet that wouldn't work well. That's one of the best things about the Bob.

I'm sure you will really like it

i have had very good luck with everything that i have fed my bob, from 100 grain Nosler bts to Hornady 117 ssts. with that said, i shoot the best groups with a 120 grain Sierra hpbt, but have yet to shoot a deer with the 120. See what your gun likes, and let it tell you. Enjoy the process! Paul

Started using the Roberts on varmints and deer back in the 70's. Have used a number of 100 gr bullets but most deer hunting has been done with hand loads and the 100,115,and 120 gr Partitions. They have all worked well.

Presently, I have a Kimber Select 257 and have been impressed with the factory 120 gr loads from federal and the 117 gr SST Hornady. Both shoot pretty well out to 300 yards, as far as I have tried it. I have never used the SST an an animal so really can't comment about it

I love the Better & Standard Bobs both:



100 gr Interlock @ 197 yds; bang-flop

That bullet is, IMHO, one which performs far beyond what it should. I am a tinkerer by nature but would not feel handicapped with only that bullet pushed by IMR-4350 out to 400.

In fall of '14 I took this dink w/ the same rifle (different accoutrements) at 75-ish yards (no LRF):



That one used the same load topped with a 90 gr GMX as these hogs, but he was shot from above quartering away and the (maybe 30 step) blood trail was one Ray Charles could follow.





These were both DRTs at 100-ish yards. I recovered this (40.4 gr, 45% weight retention) in the ham of the smaller head-shot one:



I don't think you can go wrong at the ranges you're talking with the 100 gr Interlock, Partition, Ballistic Tip, 110 Accubond, 115 Ballistic Tip, or 117 Interlock.

Good luck; I hope you'll show off photos here when you're successful!

Don't overthink this. A 100 grain Nosler BT will work great. It will give you velocity and energy enough for deer...

Yep.... or any 100 grain bullet for that matter!

100 grain bullet and the Bob is a match made in heaven. Btips, interlocks and partitions are deadly on deer, bear, coyotes, marmots, ground squirrels, feathered vermin ext, ext.... I tend to lean toward the 100 grain bullet in the bob. You wanna see pieces of coyote or marmot fly? Try the speer 100 grain bucket mouth hollow point.

Got 117 gr. pills loaded in mine right now. Last few years more than I realize looking now, family members other than me have done a good portion of the kill'n with the bob.

One of the finest white tail rifles ever invented. I have used the standard and the Improved version over much of my life. I would center my choices around the Nosler 110Accubond, 115gr Ballistic tip and the 117gr Hornady BTSP. powdr

Your going to love the Roberts! Its a little gentleman. Somewhere around 46 gr IMR 4350 and a 100 gr bullet should do it. I've used the 100 gr Sierra Gameking since the early nineties on whitetails and have the most number of in the track kills of any caliber I have used.

I"d go 115/120 Partition and never look back. The Roberts does not offer much in the high-BC range, so roll with what performs on game. Those PT bullets offer good expansion on soft tissue, combined with enough mass and heavy construction to penetrate well and give nice exits, even on poor angles. They worked for me.

+1

I agree, with proper shot placement any 100 gr.+ bullet works well on deer size game. However, poop happens. I watched a buddy hit an antelope in the elbow at 125 yds.+/- with a Sierra 100 gr. SPT and fully expected that animal to tip over within sight (could see it for 200 - 300 yds. before it went over a hill) - never did recover it, bullet did not penetrate to the vitals.
After witnessing that, I recognized the value of a tougher .257 bullet. I now load the 110 Accubond for his .257 Rob. and my .257 Ackley. So far, so good, he took a nice cow elk with it the following year.

In the past I've used the 75 grain Sierra HP over 44 grains of IMR 4064 for most of my .257 varmint shooting. My Ruger 77 RL really did well with that load. What was on the receiving end really did not.

They were also friggin' wicked in a Ruger 77 VT .25-'06.

I've got a box or two of the new-ish 70 grain BlitzKings to try out in the new .257 when it arrives. If they shoot well, I 'spect they may be my go-to small varmint bullet.

Tom

Wow. Thanks much, thats the kind of info I was lookin for. All my hunting experience is with 7mm/30 cal bullets. I also shoot a 375 win but it throws small lead school busses at em. This will be the smallest caliber I have hunted deer with, I just didnt want any surprises as far as bullet performance goes.

Bigger and/or better construction doesn't make up for bad shot placement.

Seems an awful lot of "bullet failure" stories contain so much conjecture. Seems poor shot placement a more logical explanation.

And no, that isn't a slam on your shooting abilities; as you say, things happen. Problem is we're most likely the "weakest link" not our equipment, even one as (IMHO) poor as a Sierra Gameking.

I've always found the 117s to 120s at about 2900fps to be a sweet spot for the Bob. Trajectory is flat enough to 350 or so. No need for premium bullets, that velocity makes good CnC bullets shine. Recoil is mild.

Had good performance from Speer, Hornady, and Sierra. Your rifle will tell you what it likes. And the 4831s have always seem to work best for my Bobs. Sweet cartridge!

I found this 100 grain speer bullet to amazingly accurate in my BLR with unfortunately RL12 powder (under 1/2" 100 yards groups off the bench rest when I could hold the rifle steady on a good rest) , its still accurate with H414 but not quite as accurate, only 1.1" groups, but even then it is deadly on deer.
I loaded that load for mule deer for a buddys Dad, and in his rem 700 its even better.

I have had limited experience with my 257 Roberts for the past two years but my rifle loves 115 grain Nosler BT's over IMR 4350. Deadly on deer. Also shoots Hornady 117 grain factory loads well. Low recoil makes the 257 a pleasure to shoot. Enjoy your new rifle.

Starting in 1983, I shot a bunch of deer with the 85 grain .243" and 90 grain .257" Sierra Gameking HPBTs, but no longer do so 'cause I had four failures to penetrated, two with each of the different diameter bullets. These were easy shots, under 200 yards, at unsuspecting animals and the bullets hit where they were aimed, but they came apart on contact and didn't penetrate through the rib cage and into the chest cavity. All four deer were recovered, but only after being hit repeatedly.

Now I shoot Barnes, Hornady SpirePoints, Nosler ABs and Partitions, Speer HotCores, and Winchester/Olin PPs at deer when I'm shooting smaller bore rifles and save the Sierra products for shooting varmints.

tag

Given A, how can you conclude B?

I've been using the 100 gr partition in a 25-06 loaded to Bob velocity for years. It would be my first choice.

I shoot the 115 Ballistic Tip and 120 Partition with H4831 from my Ruger Ultralight.

I suppose pieces may have reached the vitals but given how open the land was and our recovery efforts, if they did, damage caused was not sufficient to make that animal recoverable. I watched the impact through binoculars and yes, with proper shot placement he would have had his antelope (he did not compensate for wind), but I have little doubt a stouter bullet would have done the job.

260: any experience wth the 117/120 Sierras?

I have a Sako in 257 Ack Imp and have killed a few deer with it . I use nothing but the Nosler 100 gr Partition and IMR 4831.

Why the hell have I always wanted a 257 Roberts??? Got a real nice 257 Bob at the LGS that is haunting/tormenting me right now... It's a Ruger M77 with stunning wood. Holding out for a pre 64, but don't know how strong I am... Ruger's looking pretty good right now..

You might get that Ruger, it is more versatile. You can loan it or lose it and you will never miss it...

No, not a Sierra kinda guy unless I'm shooting at paper or varmints.

Buy it

I understand. Just curious what your experience might have been, if you had.

I used to use 117 gr RN Hornady and they are OK, but at close range they don't seem to open up unless you hit something solid. I was sitting at a campfire years later and another hunter said the same thing, so I doubt if it was a fluke.

That's because they're still used in factory loads for the .257 Weatherby, so have to be pretty stout. People who load them in the .25-35, because they're the only round-nose .25-caliber "deer" bullet available, are often really surprised at the lack of expansion.

They do work pretty well on lions (cougars) from a .25-35, but it's not that far to the top of even a tall pine tree. At ranges measured in feet as opposed to yards, they do expand.

I shot a big doe with 117gr Win Powerpoints and they were hell on her.

I'm rolling now. That's the funniest thing I've seen you post here. There may even be some truth to it too... Thanks for the laugh!!!!! ..

My 257 Roberts experience is positive but very limited, shot one doe at 200 yards with a 100 gr TTSX going 3150 fps using H-4350 in an old Ruger ultra light 257R, she was facing me downhill, the bullet center punched her neck and exited, re-entered her back at the ham area, exited again under her tail, obviously DRT.

Shot another doe and very nice 9pt buck with my new Montana 257R last fall, this load features the 100 gr TTSX powered to a full 3265 fps with Hodgdon's Hybrid 100 powder, the doe was on a hard quartering away shot at 40 yards, entered at last rib and exited off shoulder, DRT, the buck was broadsided at about 210 yards, center punched both shoulders, complete penetration, DRT.

I have always thought about the 120 gr Partitions in my Roberts, but damn, these TTSX's will be hard to leave.

Actually the 117 grain has worked well for me over the years in a 25-35. The Weatherby may not be going quite as fast...

I'm on my second .257 Roberts and my favourite bullet is the 100gn Hornady SP. I haven't shot a deer with it, as I always seem to have another rifle with me when a buck appears, but I have shot well over 100 pigs with both rifles. A couple of years ago I switched to the 100gn Scirocco. They are not the most accurate bullet in my rifle but I did shoot a feral billy goat at 40 metres quartering towards me and the Scirocco penetrated over 20 inches before exiting. The billy just crumpled on the spot. I've switched to the 100gn Ballistic Tip this season and will see how they go. They have been a hard bullet in my .250 Savage (20" brl) so I hope an extra 300fps muzzle velocity opens them up a little quicker. I'll save the Sciroccos for my .25-06. I may just go back to the 100gn Hornady after playing around for a few years.

Where can you find the 100gr Hornady?

110 accubonds, 115 Bergers 115 BT's are whitetail medicine

That right there is the question of the day!

I wish I'd have had the foresight concerning .223 projechiles that I did w/ thee gems !

I've used my Roberts as my go-to deer rifle for 6-7 years now. All I shoot are the 117 hornady interlocks or the 115 ballistic tips. I've shot many deer with it from 6 yards to 372yards. I switched from the Hornady Interlocks to the ballistic tips when It became clear that I was getting a lot of shots around the 300+ range. Those bullets could be interchangable with the way they act upon impact.

I also worked a 100 TTSX load up to MOA, but the heavier bullets grouped better, so I have been using them.

I inherited my grandfather's 722 with a custom stock a few years ago. Shot a doe broadside with it last November at about 15 yards, using the Nosler 110 grain Accubond factory load. The bullet hit a rib on the way in, cut the top of her heart and made a mess of the lungs, and exited. She ran about 75 yards and died.

It is not super accurate in my rifle, but it's what I had on hand. Groups run 1.5-2". The slower 117 Remington load shoots under an inch. That was what my grandfather used but I have only shot them at paper. I have handloaded varmint loads using the 85 grain Ballistic Tip that shot well too, but I wouldn't use them on deer.

Entrance wound:



Rifle:

444afic, That is a nice heirloom, enjoy it!

I have a tang safety Ruger in .257R and it's become a favorite of the whole family. My wife has made it clear it's hers to use first.

I used it for vermin shooting the 75gr Hornady HP and pushed with I4064 IIRC. It is phenominal on coyotes.

Deer have been dropped with many different loads and weights with little fan fair. I tried 100gr Nosler BT's when they were fairly new but wasn't impressed. I have not tried them since. I have however used 100, 117 gr Barnes X & XLC's and now 100gr TSX out of it. The 117gr Hornady sp work well, as did the 120gr HP when you could find them. I'm about out of 100gr X's, not that we shoot them much but use a few to verify zero, then one per animal. Then again that's pretty typical. Partitions are very good out of it as well. Mine seems to shoot 100's and 115's well, and 120's well enough.

Ruger rifles were commonly called the disposable rifle in Oz. Take them hunting and leave them as a gift to your host and it saved you bringing them home or having to clean them. They were 2/3's the price of a Model 70 in those days.

I myself just picked up a Ruger RL in a 257 roberts that was cherry. Has the feel of the Kimber at half the price. Hope it shoots as good as it handles. So, does anyone have any extra 257 brass laying around they would like to sell? Thanks, Daryl.

The 257 Roberts and the 100gr Hornady Interlock go together like ice cream and pie IMO, by far my favorite bullet in my Bob.
But, like someone else mentioned, they are hard as heck to find anymore.

Bill

I've got an ackley, it likes most everything but favors a 115-120gr bullet.

And twice as good as a POS M70

Heck my LGS has 5/6 boxes on the shelf.

Doc

My 257 Roberts shoots the 100gr BT the best and do they every kill deer!!!

I'm new to the whole .257 Roberts thing, having won a Browning A-Bolt II Medallion in that caliber as a raffle prize early last October and just in time for huntin' season.

I did all of my larger game hunting with it from October to the end of last month. I used plain old cup and core 117 gr. Hornady Interlock BTSP's over 40 grains of IMR 4350 in Nosler brass. So far, that's the only load I've shot out of the rifle. It's sub-M.O.A. and seemed to work fine on the mule deer, cow elk, whitetails, and feral hogs I've shot with it thus far.

But I'm not surprised. I might be new to the .257 Roberts but I have a three-decade long relationship with the .250 Savage via the Ruger M77RL Ultralight I bought new in that caliber back in 1985. They seem like "peas in a pod" so far, too me.

I used to use the Sierra 120 grain GameKing HPBT but for the first several years that I had my .250 Savage Ultralight, I lived fairly close to Sierra's former Santa Fe Springs, CA plant and used to buy them (and other bullets for other firearms) by the pound in paper sacks. It took me decades to shoot through all of my 120 gr. GK's. I tried the Hornady 117 gr. BTSP Interlock in the .250 Savage when I ran out of 120 gr. GK's and couldn't find any locally to me. They worked just as well as the 120 gr. GK's had for me, so I wound up using them in my Roberts.

I really like these little quarter-bores because they seem to provide me "everything I need" in terms of effective range, accuracy, and game-taking thump and penetration, but "nothing I don't" like harsh recoil and ear-splitting report.

Being such a long time .250 Savage fanboy, it pains me to admit it but I think if I could only have one rifle, the Roberts has just that little bit extra "oomph" to psyche me in to thinking that I could kill everything I want to hunt from bull elk on down with one, if it was all I had.

100 grain TTSX over 46 grain H4350, it it does not die you missed.

I like my 257bob, 722 Remington. It handles 100gr Hornady's over IMR4831 very well. The Hornady bullets handle whitey very well.

Whitey ain't that tough an animal. You put any decent bullet where it's suppose to be and whitey is gonna die.

I've started working with this Kimber Classic Select in .257. So far it shoots well with 110gr Accubonds and Reloader 22. I have some Hybrid 100v and will be trying it over the course of the summer, and will probably use it this fall. I also have a few of the rare "+P" cases.



Last season I used a .25-06 of uncertain parentage and a mild load of the 110 AB, running 3000 fps or so, and it did an impressive job on a doe, so I am looking forward to running it in the .257.

You don't need 60 grains of powder in the case to kill a deer

I have pretty much settled on the 100 gr Hornady SP in my .257 Rbts at about 3000 fps

There's one of these Kimber Select in my future.....lovely lightweight package...perfect for the Roberts.

I have one in the safe that has never been shot. One of these days, I will try it.

donsm70

As good as that rifle looks in that picture, it is even more handsome in person.

I was afraid to touch it, lest I have an overwhelming urge to take a fourth job and buy one for myself.

Guess I'll be the first to kill a critter with it. I loaned it to Carl and I think he was afraid to take it out

Tex....tax time is here.

You should sell me that Roberts!

You guys and your Kimber Selects - it's you all's fault I was forced to snag this 257 R sitting lonely on the used gun rack. Just now getting ready to work on some loads to see how it shoots...

I got one of these...they are pretty danged cute!

Is there suppose to be something special about the +p cases?

The wood on that kimber is fantastic

(edit- BOTH of them)

Good looking Knife

My latest project is a early 50's mod 70 target in the 257 BOB, It sat in the corner in a zip up gun bag for many years after the owner passed, I would make a grown man ,mod 70 loon cry ,most was fuzz but trigger bow and a few spots on out side of barrel had a few pits, some way the bore escaped all rust and is fantastic SOOO , Its going in a high comb MC stock, The crown get single pointed to fresh metal, stock gets refinished and pillar bedded, free floated.I have no option but midnight blue ceracoat, just a few to many outside pits for rust blue... Im a huge 110 accubond, 115 gr BT's and if it likes em the 115 Berger VLD's. Im calling it my old man Whitetail ear shooter! If it comes close to my 53' mod 70 shilen barreled Pacific Rimrock /Borden stocked 25-06 or a very early 25 wssm Coyote lite it will be a pure WT hammer! Photos will follow after work is done and range time happens, I love the 3000 fps, 110 gr combo!!! very best and long live the old 70's and the BOB! very best WinPoor

I'm a Ruger 257 Roberts guy. The 110 Accubond has performed well for me.

My latest was a hog hunt in Mississippi. My .257 Roberts started out as a Pre-64 Model 70 Super-grade that someone had butchered the stock. The rifle is wearing a Legend stock from Echols with Zeiss glass and S&K mounts.

I shot the first hog behind the ear at 50 yds. DRT. The rest of the flock busted out of the cover and ran. I shot 3 more hogs with my next 3 shots as they crossed the ATV trail. The running hogs piled up in a 10 yd. radius.

Clickty-Clack Bang.... Clickty-Clack Bang.... Clickty-Clack Bang. Love that sound!

I thought the govt bought the guns back from the kangaroo fu&#%rs? Pre 64 mod 70's dont work down there? LMAO v best WinPoor

I can smell the smoke from the cooker/grill from here Whitbird

Well done.

I brought my Montana in 257R to the pig hunt, didn't get it out for fear someone would make an offer on it, still don't know if I like it enough to keep it yet.

Sorry for the late reply.

The tiny little +P on the case head is worth 200 fps

Seriously, when they were introduced I read they were stronger, and could take loads higher than std cases. The factory ammo so stamped is a few thousand psi hotter than standard Roberts loads. I just looked, and it appears both Nosler and Winchester sell +P brass.

i have no idea what mine are but I put up to 47 grains of H4250 under a 100, thinking about the Barnes 80 grain as well. I really at this point in my life have revised my opinion/knowledge. You don't need a 100 grain copper bullet for a deer.

Just starting to work up loads for my M70 (1981) in 257 Bob. I am having to seat bullets a lot deeper than I want due to the short box restriction. Other than that, cool gun/caliber.
Tim

100gr. Speer BT has worked well for me on deer.

Wasn't the +P designation used for factory ammo and meant for modern guns? I seem to recall that you can load any modern brass to "+P" pressures and be fine. Am I wrong?

That is my understanding as well. Modern 58,000 PSI vs Standard 54,000 PSI. No difference in brass.

But I have been wrong before

I started with the 257 in the mid 1980's. My rifle is a Mannlicher 1952 model and a low power scope. Usually a Leupold 1.5x5 or something similar. We don't have to shoot very far down here. I always had great luck with anything that weighed 100 grains. It is just not complicated when what you hunt is deer and you pick your shots, which I do with anything I shoot. Great round. I am now using a Sako with an after market barrel. I'm saving my Mannlicher for my Grandson but I'm still using any good grade 100 grain bullets, Sierra this past year.

You hardly ever see a .257Roberts being used over here, it seems that the introduction of .243win was its death knell.

Its a shame really as I suspect the Roberts is actually a bit more versitille than the .243win, and for larger deer, I would much prefer the 115 to 120 grain bullets that are commonally available for the .257 Bob...

308 tell me about the stock on your m77. I have one that looks very similar . I thought it was a light weight version when I first saw it in the LGS but it is a std tanger that someone reworked the factory stock on.

It is a Ruger Hawkeye factory ultra light, 20" barrel. Stock measures 30-1/8 or 1/4" from tip to center of butt stock not including pad or spacer.

308, Your Ruger UL is solid gold.

I have not read all the posts, but will add my limited experience.

I have an 03a3, with a 24 inch Douglas barrel 1/10. The load I used was the 100 grain partition, pushed by 3100 powder. I couldn't tell you how fast they were going, the end results were the same DRT.


I also loaded some v-max of 75 grains, they were my varmint load.

I love my .257! The pics are of last year. I used one of my Whelens last year, but my Dad got his first deer with his "hen's tooth" 760 in .257. Took many years of looking for one for him and finally almost tripped and fell into one that had been in a friend's closet for years. (It was a "Oh, do you know anybody who buys old guns?" moment...) He has quite the collection of original 760 Amish AR-15's. Still looking for a .222 and one stamped .244, other than that he has them all...

I believe Dad was using 100gr Sierras, and knowing him it was a mild load. We both have Mausers in .257 also. Have used everything from 87gr to 120's. Seem to like the 100's the best. My mauser I am ashamed to say LOVES Remington factory 117gr loads. But the deer sure are dead quick.

The first 257 Roberts I owned, was picked up just a couple of weeks before the whitetail opener in 2003, if I remember correctly. The first load I put together shot well and so I just went hunting with it.

The 90 grain Sierra HP Gameking laid three out on opening morning, and all three were bang flops. One was a neck shot, one a spinal tap, and the third a high shoulder. I don't think any one of the three exited, so in the years to follow, I haven't used that bullet again.

I traded that rifle before hunting with it again, but bought a 77mkII Ultralight for my son to hunt with when he turned 8. I loaded the 100 grain Hornady with a starting load of H4350 and we each took a deer that fall with that setup. It worked fine. No muss or fuss and with exit wounds too. The blood trails were short and the deer died in sight.

Subsequent years have seen us use that rifle with the 110 grain Accubond, which also worked well, although I can't say I felt it did a "better" job than the 100 grain Hornady.

I think it has been a few seasons since we used that rifle. Both of us have been tinkering with other cartridges, but I'll just about bet it sees some time this fall. (I've actually been shooting the fraternal twin of the 257 Roberts, the 6mm Remington.)

I would most like to work up a load with a bullet in the 115 to 120 grain range to see how they work. I made a run with the 115 grain Partition a few seasons back, but the accuracy didn't want to gel for me, so I ended up putting the rifle back in the safe and went with something else.

Maybe this year.

What kind of accuracy were you getting with the 115 Partition? I've found them pretty easy to get to shoot in several .257's, but my accuracy standards may not be as stringent as those of some other hunters.

I have gone back to 115 partitions in my .257 AI--I just could not get the 110 ABs to shoot as well. First time that has happened to me with ABs, and I shoot a lot of different weights of ABs in several cartridges.

I load 100 ABs for one on my grandsons in his .257, and they shoot lights out. Killed a mule deer with that rifle and bullet combo a few years ago before I sent it back to him.

I had a Browning A-bolt hunter that would shoot the 115 npt. into 1.5" five shot groups.It liked the 100gr. Sierra better.I also had a Ruger M77-UL,that was a nice looking gun,but,it was so muzzle light that I just couldnt shoot it well from field positions.The only Bob I now have is a remington mtn. rifle that shoots everything that I have run through it pretty well.

I may have been overly picky, but if memory serves they were closer to 1.75" to 2" than they were to 1.25".

Admittedly, I was also working with a 700 ADL in 6mm that was shooting 100 grain Hornady SP's into an inch with the first load I cooked up.

I elected to go with the 6mm and benched the 257.

I'll give it another go this fall, for sure.

That wouldn't please me, either!

Generally I've found 115 Partitions to shoot an inch or less (often a lot less) with the old standby IMR4350, or the new standby H4350.

I think the 115gr Nosler Partitions shoot best in my
Model 70 257 Roberts. The 110 Accubonds are almost as good.
Best powders were RL22, Norma MRP and H4831SC.
