Getting another .375 H&H and in this one gonna use a bullet in the 250-270 gr class. Thinking of using a 250gr Swift A-Frame,270 gr SAF,270 gr Woodleigh RN and the 260 gr Nosler Partition.

The Woodleigh RN has a impact velocity of 2400 fps and if I can get 2600+ in it,what will happen if I get a very close shot?

e: For ultimate bullet expansion and results, it is recommended that this bullet be fired in a load with an impact velocity no greater than 2400 fps and no less than 1900 fps.

This is what Woodleigh say's.
The above is what I copied from Midway's page.

for NA use , the 260 accubombs are good to go.........

Include either a 250gr or 270gr NorthFork in your list....

I got some 250 TSX's to try. I plan on checking'em out after deer season.

That bullet makes a lot of sense. We'll see what my NH SS M-70 Classic will do with it.

DF

Here are two bullets shot from my 375 RUM. Both are 300 gr Swift A frames, shot at a herd bull Bison from 190 yards and recovered just inside the far side about an inch shy of exiting. At 190 yards, the impact velocity should have been about 2250 ish. I know these slightly heavier boolits than the 270 gr you mentioned, but just a reference to a 375 300 gr Swift A frame. Hopefully I'm talking apples to apples.

Looks like you more than "shot at" that bull...

DF

True that

I don't have a scale, so I don't know the weight retension, but it looks acceptable.

elk, last fall I used my .375 H & H on a large cow moose, and a large cow elk.. Used the 260 Nosler Accubond.. I have use Accubonds in several other rifles and had excellent results.. The moose was a couple hundred yards.. good neck shot did the trick.. the elk was at least 400 maybe a bit farther, there was a good bit of drop I held over the back and hit low in the chest.. She went down immediately.. I think for most of the hunting we do short of brown bear, this bullet would give the best of both worlds.. It holds together and is fairly flat shooting and packs a good punch when it hits.

Thanks fellas. Was/is considering the 270 gr SAF as a one load do all in this .375.

The Woodleigh has such a low impact velocity that I am concerned about it's use on BG.

Also,this is not for NA only.

I use Barnes TSX 270 gr. and TTSX 250 gr. in my .375 Ruger, with total satisfaction in the results. They have been used on game from Springbok up thru wildebeest, sable, nilgai, and Asian water buffalo, with perfect results. If they shoot accurately in your rifle, I highly recommend them.

How do you compare the two, velocity, accuracy, performance on game, etc...

DF

In my .375 Ruger Hawkeye African, I handload the 270 gr. TSXes at 2800 fps MV, the 250 gr. TTSX at 2880 fps MV. Accuracy with both is similar, both being sub-MOA, with possibly a little edge to the TTSX. The TTSX has quite an edge over the TSX in BC (.424 vs. .326), and it flies a bit flatter due to higher velocity and BC. Sighted in 1.5" at 100, it is dead on at 200, and a hair under 7" at 300 yards.
I don't know if those velocities can be safely achieved in an H&H, but they are easy loads in the Ruger.
As far as performance on game goes, they both expand, penetrate, and kill stuff. On small stuff like springbok, expansion with the TTSX is sudden and complete, and leaves big holes. I've only recovered one of each from game, and they look identical.
Unless really large African game is once again on the menu, I suspect the 250 gr. TTSX will see the most use in the future.

If your worried about low max impact velocity on the Woodleigh RN bullets go with the Woodleigh PP bullets. Hunting Die Specialties carry Woodleigh bullets in stock. I got some Woodleigh 350gr. PP that I am going to try in the 375 Ruger. I emailed Woodleigh and got load data from them. By their data I should get 2360fps with RE17 powder.

I'm a fan of the 250 gr in the 375H&H. With RL15 it isn't hard to get 2875-2900 with RL15 in rifles I have worked with (mostly pre 64 M70,s,SS Classics, and Krieger barreled customs).

Trajectory is about like that of the 30/06-165 or 270-150.

I use the Bitterroot 250 but see no reason why the TTSX,NF, or Aframe should not be just as good. I use the 250 Sierra for practice and POI is the same as the BBC with the same powder charges. Easy to load, forgiving and very accurate.Pretty simple.

They make big holes. As Bighorn says,reports here and from others say the 250 TTSX is a very good performer. They are all bombs from a 375 bore rifle.They can be used on anything here including brown bear.

This is not only going to be used in NA.

Used the NF's in a .358 Norma and they left a nice big hole in the oryx. Gonna have to look them up online.

Still think a 270 gr SAF or NF would do want I want.


Looked at the NF website and they have a 20 count sample pack.

By the way the .375 I'm getting is a Winchester M70 Classic Stainless steel and it has a Weaver 3x on it.

Last month, Noslers' Shooters Pro Shop had a great buy on 260 gr PT over-runs. I bought 3 boxes.

If it's the older NH SS Classic, the 24" barrel, IMO, is way too heavy. These guns do well chopped to 21" or so. They handle much better in this configuration. This one has NECG irons and I tweaked the NH trigger to a crisp 3#'s. I like this gun, even with the Tupperware which I Steel Bedded after jerking the hot glue bedding out with a pair of pliers. It will cycle EMPTY .375 H&H brass thru the action as fast as I can work the action. Not many guns will do that. And, it shoots...!

DF

Barnes. From 235-300 accurate and deadly. Many Buff PHs suggest the 300 TSX is better than solids.

My "1 of 1" Shot show A bolt has a 26" bbl (I'm not chasing Buffs into thornbush) and will push the 235 at 3000. Same trajectory as a 180 in a 30-06. 3 in 1" all day long.

best, Larry

Kynoch loads the 270 RN Weldcore to 2650fps.

DF,I had one these way back in the mid-late 90's and regretted trading it off. Not gonna get rid of this one.

Pretty much going to leave it has is.

Wonder then if the impact velocity is a mis-print or for another bullet and they are mixed up?

No, Woodleigh does recommend an impact velocity range of 1900 to 2400fps for peak performance with the round soft nose version of the 270grain Weldcore, but they recommend an impact velocity range of 1900 to 2700fps for the protected point version of the 270.

Kynoch loads the round nose version to 2650fps, and it is available to obtain feedback from users and/or you can try the load out for yourself on game, before working up any handloads.

The performance of the 270 gr TSX behind RE15 at 2700 - 2800 fps is near legendary and would be, actually is, what I would use. I have used the 260 gr Partition on a couple of elk many years and, of course, all was good.

Thanks fellas.

For H&H or Ruger lower 48 use, I wouldn't go heavier than the 260-gr AB or the 250-gr TTSX. Flat to 400. And if ballistic reticle or turret, further.

I used the 270-gr TSX out of the H&H in Africa and it just flattened PG. I see the 250-gr TTSX as even better especially for the elk canyons and meadows. I also have found the TSX/TTSXs very effective amd very accurate across several calibers.

Edited for clarity.

How many grains of rl15 are most of you running with 250 or 270 tsx's? Mid 70's?

I use 76 grains with the 270 TSX. It does just a tad over 2700 in my Dakota and is EXTREMELY accurate.

Thanks Glenn/neighbor, A buddy just picked up a Dakota in 375 H&H and it's a real beauty. Mine is a Winchester model 70 Super Express.

SW, where are you here in KS. I'm in the OP/Olathe area. I hope your buddy's Dakota shoots like mine! He will be thrilled. I always wanted a M70 version but never picked one up

I guess I should add that I've seen loads lower than that as well but don't know what guns they are in. Barnes manual is higher and my velocity is in line with manual with no pressure signs at all but I'd start lower for your gun to be certain. But, it's worth it. That bullet and velocity is a hammer!

With the 250 Sierra and BBC I use 76 gr for 2875 and 77 gr for 2925 from a 24" Krieger SS barrel. Bet the TTSX would be pretty close.

I like to burn H4350 with 270 gr and up.

In my other .375 H&H,use 79.5grs of H-4350,Rem 9 1/2 mag and the 300 gr Sierra GK.In the 24" barrel it's getting 2630 fps.

In the "new" one thinking about using RL-15 and maybe Var-Get with some sort of 270 gr bullet.

Even tossing the idea of using a 300 gr in the "new" .375.

I have this rifle, and the 260 Partition and a book-max charge of RL-15 is very accurate. Not much I'd not hunt with that, and it will be used on Brown bear in a few years.

elkhuntr: The folks I hunted brown bear with, said, when a client shows up with a 338 they want to know..."What bullet?"

But when they show with a 375,they said it doesn't seem to matter....they are all good.

BobinNH,

I really like what I see from the Northforks. I haven't stuck any into any game animals yet, but as far as a bonded bullet that'll expand excellent up close and seems plenty soft enough to open further out, they seem very good.

These are some shots of the .358 270 Northforks from my 35 Newton at around 2700FPS. This was sticking out of the back of the 7th jug.







Here was the same bullet recovered from behind the target stop at 200 yards.



I know the .358 isn't a 375, but the frontal area is only going to get bigger with the 375.. Just wanted to give you an idea of what they will look like.

Beretzs,IIRC I used the 250 gr NF in my .358 Norma at around 2800 fps. They left a good size hole but did not recover any bullets. Hit it with the first shot and as it ran off I put another in it,it ran in a fishhook pattern and died about 100-150 yds away.

According to the people when it was checked out,it was a female,18 months old and about the size of a large Mule deer. It was so tender and delicious.

The rifle,Ruger M 77 tang safety re-barreled to .358 Norma.




The oryx.

Killed it in January 2008. So the kids are 10 yo (boy) and 9 yo (girl).

I am down by Wichita in Augusta. I have been wanting to try Barnes and RL15 combo so thanks Glen and all for info.

He has several 375's including a nice merkel double but that Dakota he just got is a real beauty. He really doesn't have a choice I am going to test it out. We start Friday afternoon range sessions in March I am ready to start some laod development.

Have been using my .375 Number One as a black bear thumper. It's doing a fine job, as you might imagine, with the 260 gr Nosler Accubond.

This one was recovered from the far side, hanging in the hide, of a bear finished off at about 10 feet.



I've found the 260 Accubond extremely accurate, and have thumped a bear a bit past 300 yards, no problem. That shot blasted right on through and dropped the bear instantly. I liked that.

Regards, Guy

What's your load, Guy?

Stolen directly from Mule Deer/John Barsness:

69 grains of Reloader 15
260 gr Nosler Accubond
2620 fps - mild load
I'm using Federal magnum primers

Accurate!

I was a little surprised to capture the bullet. It was hanging in the off-side hide, backwards. The mushroom kept it from going through. Had punched a couple of them through our 300ish pound black bears in the past.

Guy

Damn, now you tell me... ...That's all I use in my 375 H&H and it shoots alright. I'm always looking for the "blemished" bullets though. My bad!! .. :



Don't pay attention to the crappy shot placement. Posting picture for load data purposes only, for my buddy elkhunternm. I figured this bullet weight would be very comparable to the 250's I use in my 338 win mags for elk hunting. They always hammer the hell out of them, so whey not the same same with a 375 H&H running 260's. Good luck with that beautiful classic stainless my friend. It's a nice one!!

Thanks BSA,have RL-15 and IMR-4350. Have used the 260 gr NP in my other .375 but it likes the 300 gr Sierra better. Which is why I want to try a 260-270 gr bullet in the "new" one. If that makes sense.

Ha ha.... No not really, but it's you and I understand...

Knew you would.

Should have some 260 gr Nosler Partitions by Thursday of next week.

No problem, I would have shown you my 73 gr. charge with RL 15, but it's a little stiff and my rifle doesn't like it as much as the 72gr charge:



It's a pre 64 and not really accurate. She is what she is:

Nice.

Took it out this morning and with a 300 gr NP and it shot about 1-1/4" at 100 yds. Now,when the 260's arrive we'll see if they are better,same or worse than the 300's.


Yes,I know that the 300 gr NP is just about perfect for anything in the world,but,want to try a lighter bullet,cause I can.

Keep an eye out for the 260gr. partitions at SPS. They have some damn good deals on their blemished and over runs there.. Rifle sounds like it's got a lot of potential. That's always good..

Have a box of 260's on order from a LGS. I go to SPS at least once a day to look for some bullets.

Have you been to SPS lately,they have/had 210 gr Nosler Partitions in .338" there,if you're interested.

Here you are lads:
Safari Express, 300gr Swift Aframes & Hornady Interlocks. 76gr H-414 F-215 primer WW cases, 2550 fps:


Recovered from eland, wildebeest, zebra (last one is a 180gr Hornady from an impala and a 300 WBY. HINT: USE TTSX now):



300gr TSX 74gr RL-15 F-210 primers (JJHACK's Load):



Note: Barnes solids shoot to POI as well.

Nice shooting' there Jorge.

Indeed!

Yup.

Taught him everything I know......And he still shoots like that!

This fella was 260 gr Partition'd many years ago

Nice bull.

And 260 gr Partition-ized that's even better.

Gents; I've since gone more to the TSX in 270 and 300gr with practically the same results. I've developed loads using the 270 TSX and the 300gr Barnes solid that shoot to POI @100 yards and that is what I would use whenever I get back across the pond and right now, I have no prospects..

Powder burns on that target...??

That IS good shooting...!

DF

In my best Texan drawl...Poor Jorge he can't hep it...

Now you're channeling Swampie!

Nice discussion and shooting Men, the 270 gr tsx has become my "ALL" 375 bullet for hunting, the H&H will push them to an easy 2800 fps, the AI version settles nicely at 3000 fps, both have the accompanying 300 gr Barnes banded solids for no other reason than that they seem to go together.

Hell, may find myself in Africa some day carrying either of those rifles.

OUCH!!

You really know how to hurt a guy...



DF

I need to send you pics of my 'rube goldberg' 375 AI.

Post'em.

Or send me a PM. I'll do it for you.

DF

PM on the way.

The Rube Goldberg .375 AI is one beautiful rifle. I tried sending the I-Phone photo I got from gunner, to my email for upload to Photobucket for a link to post.

I keep getting "error" messages out the gazoo, my email not receiving my I-Phone photo. So, no photo for Photobucket upload.

Maybe my equipment doesn't like gunner's equipment.

In this cyber world, who knows. I know just enough to get me in trouble.

Anyway, no photo to post. But, it's a gorgeous rifle. Unfortunately you guys, at this time, will just have to take my word for it...

Maybe one of you can send gunner a PM, get his info and a download of that photo to post.

DF

Awesome shooting Jorge. I always love seeing excellent shooting 375's.

Thanks anyway DF, 'ol Rube must be a shy cat out in i.t. land.

Yeah, ole Rube's obviously a modest sort, not wanting these Fire Loonies drooling all over their keyboards...

DF

, maybe so. lol

Have the 260 gr Partitions now,gonna load some up to try on Sunday.

Good shootin to ya Elk, have fun.

Yeah fun,taking a .375 & a .338 Winnie shooting Sunday morning.

Remember elk, Elmer told us recoil is all in our heads.. Didn't try the 260 Part. but used the Accubonds on an elk and moose this fall.. Excellent.. Good shooting..

WCH,could be. After shooting a .338 RUM with 250 gr Sierras at 3000 fps,that sure rattled the noggin.

Tried the 260's (NP and Accubond) in my other .375 and they just did't work to my satisfaction. Hoping the NP's will work better in this .375.

You and gunner going varmint hunting with those rifles???

Yup.

It's all good in da neighborhood brudda.

..........................prairie dog 2 o'clock.....BOOOMMMMMM........................pd gone, trench cut for pepper plants, 2 o'clock long.......................out. lol

gunner gets all excited just thinking about that...

That's just peanuts compared to shooting Okie dillers with a Gibbs.

DF

dillers with sticks would trump prairie dogs prone, ouch.

I had to think about that one for a minute. I could see those dillers swinging sticks...

Then, I understood. Shooting sticks would be better practice for DG than PD's prone...

DF

, Oh hell yes. lol

Yup. Shoveling is for wimps.

elk, I'll bet that 338 Ultra did rattle the old noggin. The .338's seem to give me more punishment that either the .30's or the .375's... But they are fine calibers..

Yeah, I've had a .338 WM and a .340 Wby some years back. They both went down the road. Some folks love them, I could never warm up to either.

Now, I really like my .300 WM, 9.3x62, .338-284 and .375 H&H. Just didn't care for the .33's.

DF

WCH & DF I love the .338Win,RUM and the .340 Wby. The Wby brass is expensive and the RUM will do what the Wby will do.

Have in the gunsafe a Winchester M 70 Super Grade .338 Win and a MRC M 1999 .338 RUM.

elk, never had the .338 rum.. Shot one that belongs to a brother-in-law, but it was ported.. Sold my .338, but still have brass and dies, just incase something comes up I can't resist..

Do have a rebarrel job on a 700 in .340.. Made my brass from Rem. 8mm mag. good stuff, had to trim some.. But I am certain, there is little difference between it and the Rum.. Don't shoot it much anymore, but still can't bring myself to part with it..

I am sure from watching your posts, you suffer from the same thing I do.. Buying is fun, but selling is tough..

Your mention some where of buying a .458 reminded me this a.m. of one I missed years ago.. A Remington C grade for about $600.. Beautiful rifle.. When I got back to Wy. from the trip, I called the gunshop and told them I would take it.. It had sold the day before!!! Still think about that rifle everyonce in a while.. Would have made a great antelope rifle!!!!

WCH,buying is fun,shooting them is fun,keeping them well that depends. The two .340's were Wby rifles and do sort of miss them but not much. Wouldn't mind having a .340 in a Mauser/Winchester CRF/MRC action and a good piece of wood.

There have been a few I got rid of that I wish I hadn't.

There was a Win M 70 .458 Win at a gunshow a coupla weeks ago,he wouldn't do a trade.

Probably for the better,most likely I would've shot it a few times and then tried to get rid of it!

That is so funny and probably true as hell If I know Gunner...

My 375AI is going PD shooting this summer. Partly because two cousins are coming up from Texas to go on the shoot. I'll be sure to ask them about how big PD's are in Texas. Besides I need soemthing to shoot at with that new rifle and PD's are about as good as paper targets. If you can hit a PD at 200 yards with a 375 regularly then it ought to be good enuf

I finally got gunner's .375 AI photo off my phone and on the computer.

Here it is.

Maybe gunner will tell us how he took a box of gun parts and crafted this very fine rifle...

DF

Let yo Texican kin shoot that big gun, more the better...

You know, they can't complain about recoil; that would taint their image as bigger than life Texicans...

DF

That's right, we'll just drag a little dirt over the seeds with a drag rake.

Sho nuff BSA, you should have seen the trench when NHK9, Rockchucker, rattler and Mac went after that solid outta my 500 Nitro after K9 killed it at a pig hunt one year. ROR

Thanks for flushing 'ol rube out in the open DF , the action came from a shot out 7MM STW Laredo I bought back about '94, 140 gr 1st gen ballistic tips at 3600 fps didn't take long to torch the throat. lol

I got the stainless barrel, sights and all from the old Gun List paper that used to be at the local newsstand, it was a new pull-off in 375 H&H, had my 'smith run an AI reamer in it and set it up.

At that point I let it sit in the safe for a decade doing nothing, kinda looking around for a nice walnut stock.

About 2003 I called Great American Gunstocks out in Cali, think that guys name was Paul,? anyway he agreed to sell me the stock that had been ordered and never picked up by the previous customer, it's a really nice stick, I got it for about 60 cent on the dollar and the 14" LOP is perfect.

Sent the stock, and barreled action along with the crappy [Laredo pot metal] bottom metal back to my 'smith for fitting and bedding, it turned out absolutely perfect imho, it's one of the most accurate 375's, or any other heavy medium bore I've ever fired.

Never did like the pot metal bottom metal, and this is where YOU came in, I thought, hell, it has a stainless barrel, why not some nice stainless bottom metal, saw you had some available, sent ya a check and there she is.

Had a set of Talley bases and QD rings along with a spare 2.5-8 matte Leupold, gingerly lapped the rings, cleaned em up and presto, she's ready, zeroed the factory irons dead on a 50, the fireform loads with the 270 gr TSX bullets are more than accurate enough for hunting, no need to waste em for cases.

So there's the story about 'ol Rube the 375 AI, oh, and because she is such a "no-pedigree" critter I outfitted her with one of my favorite slings, a Galco RS7 9 strand leather.

BTW, Thanks for the bottom metal, it was a perfect fit, and the pic too.

Gunner

Had forgotten about you ending up with that SS M-70 bottom metal. That was off a .300 RUM donor that I turned into a .404J. I used Williams bottom metal on that build, thus this bottom metal was surplus. Should have recognized it...

I like ole Rube...

DF

Nice "varmint" rifle there Gunner,give you $100 for it,cash.

Now, I thought the picture was better than that...

DF

10-4, 'Smith said he had to buff [polish] the edges to make her fit, no gap no slop, just right.

Now Elk, I got you moved in the front of the scope repair line , I like you, I couldn't take advantage of you selling you a 'salvage' rifle.

You're right Gunner,you can keep your "varmint" rifle.

Thanks Main, hit anything with that 6X yet?

Nope,I quit callin' coyotes around the first of the year and the jackrabbit's are few and far between.

Dang.

Only coyote I called in I had my .22-6mm and tried to kill it without a shell in the chamber! I'm getting old.

Yep.

Those "clicks" can be pretty loud...

DF

Yup,they are.

Daymit, as long as we don't do that with our CC pieces.

Maybe next time I'll take my .375 H&H,that "click" should give a coyote a heart attack!

Hell Yeah, 30 lb M-70 spring, craakkkkk! , you should hear my Mausers.

I gotta a couple of Springfields.

They'll whack a primer about as hard and click about as loud as a Mauser...

DF

The Springfield has a American accent "click" and the Mauser has a German accent "click." I know cause own both.

Have both, too.

I'll have to listen more carefully to what they're saying...

DF

I didn't know what they were saying until I got hearing aids.

Yep.

May be about that time for me...

Too many big guns, too many years...

DF

Yup.

Also been married for almost 18 years.

Hmmm...

Now that sounds like a "selective" hearing deficit...

Bet you got those hearing aids just to save face...

DF

I'm staying away from those damn hearing aids. At least that way, I'll have a good excuse!!! ... Going on my 19th. year of marriage so I need all the help I can get

Actually it was my wife,kids and my parents who finally put their collective foot down.

Still have "selective" hearing.


BSA,as far as the hearing aids,they are good until I'm around very loud things,then not so much.

Congrats to your wife for putting up with you for almost 19 years.

Got back from shooting the .375 H&H and the .338 Win.

The .375 H&H with 76.5 grs IMR-4350,Rem 9 1/2 mag,260 gr NP shoot the best. About 1" or a little less at 2595 fps average,gonna load some more of these and take them out to try again next weekend.

The .338 well,may try RL-19 next with the 250 gr Sierra or try a different primer with IMR-4350,like a WLR or CCI-250 mag.

Ha ha. She's a damn fine woman and really deserves some kind of an award!!!!!! Cool that you finally got out and shot your 375 and 338. I was beginning to wonder... . Hey by the way, use the CCI 250's...With the 338, start at 67 grains (IMR 4350) and work up 1/2 a grain at a time. Seat the bullet .020" off the lands and you'll find a good shooting load in no time... Here's how my rugers always shot:

Yeah,she does.

Thanks for the info amigo.

Shoot the 260 gr NP,76.5 gr of IMR-4350,Rem 9-1/2 mag primer and it shot into a 1-1/4" group,so I'm done with "load developing" as it will do for whatever I want to hunt with it.

I shot a 54" bull moose that I called in. I shot him in the chest and exited the last rib w/ a .375 hh using the 250gr TTSX. Love that bullet!

Have wondered about that 250 gr ttsx since it came out Green, I have a pile of 270 gr tsx's and my rifle loves em, will even shoot em a bit over an inch at 3100 fps in my 375 AI, I've backed em down to around 3K and they shoot even better.

gunner500,
I have similar experience as you with my AI,and will be experimenting with the 250TTSX this summer because of the much better BC. Perhaps we could share info,depending upon who gets the work done first.I probably won't get started until July,as I like to developers loads on "hot" days! I'm hoping for 3k or better and 1/2" to 3/4" 3-shot groups. memtb

10-4 memtb, you can easily get to 3K with the 250 gr ttsx using RL-17, my rifle is a M-70 with a 24" barrel, agreed on the hot weather workup, especially on medium to big bore rifles that may be taken to Africa and put into service on or around dangerous game.

gunner500,
I finally found some RL17 several years ago,and it's everything that I could ask for in a powder. Real good velocities and the best accuracy of all I've tried. I also did a test at sub-zero temp's(left rifle and ammo outside several hours before test), and according to my chrono,actually gained 9 fps. And,got my best 300 yrd(sub 2") 3 shot group. All in all a very good test day. memtb

Now that's what I'm talking about.

Mirrors my results to the tee.

Gunner,

What's a good RL-17 load, 250 TTSX in a .375 H&H, not AI?

ElkhunterNM, 2595 fps seems a bit slow for the 260 Nosler out of the .375 Holland. That's almost .375 Winchester performance. My hunting loads with 300 Noslers run around 2575 fps with W760 and N204.

Does your accuracy go south when you speed up the load? And did you find pressure issues pop up when you went faster?

I'm not being critical, but I just bought 3 boxes of 260 gr overruns from Nosler's Pro Shop, and judging from the load data, a guy should safely be able achieve around 2850-2900 fps with that bullet.

I'm going on a coastal grizzly hunt this fall and was thinking that I'd try the 260 Noslers, providing they shoot well....

As the speed went up the groups opened up and no pressure issues. I'm a little disappointed in the speed,but not to worried about it. It's only 100 fps slower than I want and there's not a animal in the world that is going to know it's 100 fps slower.

In my other .375 H&H I use a 300 gr Sierra GK,H-4350,Rem 9-1/2 mag and it's getting 2630 fps.

Good luck on your coastal grizzly bear hunt.

Don't know DF, haven't played with any of the 250's yet.

Mine loves 75 gr. re 15 and 270 gr. TSX's damn near a one holer! Probably one of the most accurate rifles out of the box I have ever owned. Model 70 classic stainless 375 HH. As always work your loads up from proven data.

I keep seeing reports on the superb accuracy of the 270 TSX vs. less than stellar reports on the 250 TTSX.

My Ruger Magnum loves 300 grain Swift A-frames. I see no real reason to use anything else that needs whackin' with a 375 H&H.

Can't speak to the TTSX as I have only run the TSX. They shoot so well I was not even planning on trying anything else.
