Home Forums Hunting & Shooting Hunting Rifles 257 weatherby

So I recently got one its a rem 700 it was a limited run they did for rmef 25th anniversary few yrs back, anyhow all I read about is folks using 100gr bullets.. I was wondering why the 100gr bullets. I did work up a good load using 115gr tsx using 70gr of 7828 and fed 215. It also shoots the 117gr hornady btsp very well.. The 115gr partition showed potential as well..

My 257 Wby does best with 115 gr bullets.

Many owners like the 100 gr bullets for the very high velocity, which is what attracts most buyers to this cartridge in the first place.

The only 100 gr bullet that excels in my rifle is the Hdy Interlock. It destroys an awful lot of meat at such high speed on closer shots, in my limited experience.

I think the heavier bullets are a good match for this cartridge.

I use a custom ruger no. 1 with a 257 weatherby mag 27 inch bonx barrel on it now.it shoots 3800 fps with 100 gr. bullets I use swift a-frame bullets .have shot a lot of animals with a 257 w.mag and swift a frames seem to work the best and don`t damage so much meat.you have one of the best cartridges ever designed to hunt with for deer and antelope,does not matter if its 50 yards or 400 yards just put it on the animal and pull the trigger !oneshotpete

I'm generally not a speed freak but I had my 257W built to stand on the throttle.
The 15ish extra grains is like adding a governor. *grins*

Any of the bullets you mentioned will work quite nicely.

I shoot 115 TSX in mine, it actually has a lower bc than the 100 gr version IIRC.....

I have had excellent results with the 115's on deer and a couple of coyotes

The new Ruger No 1 with a 28" barrel should be awesome. Been thinking about one...

John Barsness recommends the 115gr or 120gr Partitions. I follow suit, however I've killed many elk and deer with a 117gr Sierra and 117gr Hornady over 70gr RL 25 with excellent results. The partition tends to penetrate a little deeper than the others mentioned.

Pass me the 110 gr Accubonds over R-22.

I own the same rifle. It loves the 100 gr. Nosler Partition, and so I've never really needed to try anything else. I shoots sub 1 inch groups, and the load I use has been chronographed at 3,785, which is just fine with me. I've shot five mule deer bucks in Montana with it, all died quickly after one shot. As a mule deer/pronghorn cartridge, well, I don't know if there is something out there that is better.

The 115 Berger is another option. There are four of us who use it primarily for coues wt. But other animals have been taken including elk. This bullet has had many animals fold to the shot and never take a step.

Totals:
My rifle:
7 coues wt longest shot 525
1 antelope 580 yds
1 javelina 328 yds
Dan’s rifle:
6 elk and 4 mule deer in Co
1 javelina
Tim’s rifle:

I have the same rifle you have as well. I run the 100 gr TTSX in mine because like SKane said it was made for speed. Believe me it will handle most anything you would want to use the 25 Roy on. It is a great round and you will be amazed at what it will do.

I shot 117 gr. Sierras out of my Wby Mk V .257 for years, with mixed results- after a couple of blowups on mule deer, I went to 100 gr. Barnes TSXes, and have been completely satisfied with the results. Most recently, tried the TTSXes, with identical results as far as I can tell- .5" groups and excellent results on game. Pushed at 3700 fps out of my Mk V, sight-in of 2" high at 100 puts it dead on at 300 yards. I have shot everything from coyotes to elk with the 100 gr. Barnes bullets, and see no reason to ever change.

I'm going to have to find some Berger bullets

Had dreamed a .257 Weatherby for decades but just could not warm up to the Japanese made guns....and I never really cared for the high comb Weatherby stock.

When Remington came out with the 700 CDL stainless/fluted it was just what I was looking for. Found one NIB on GunBroker under wholesale as it had a scratched stock. Added a Shepherd 6-18 scope and then looked at bullets and powders.

Decided on the Speer 120 SBT as it had one of the highest BCs out there and they were not that expensive. And at this point I knew the rifle probably wasn't going hunting for a while anyway as where I hunt with the exception of one deer, all shots of mine and all my friends for the last 12 years have been under 100 yards.

Ended up with a load of 70 grains of Reloader 25 that clocks 3175 fps...and runs .3 MOA.

Have been looking at the 100 grain Swift Scriocco and will probably try some next summer... Only thing that I may do is put the nice stainless action into a B&C stock...



68 grains...



69 grains...




70 grains...




..as soon as I hit 71 things started to spread...




Not a glamorous bullet but it shoots...

I'm a big fan off the heavier bullets for the 257. People tout the 100's for their velocity potential, but the problem is, their BC's are horribly low. By the 300 yard mark, the 115's are going just as fast, but with substantially more energy and less wind drift. Beyond 300 the 115-120 gr bullets walk away from the 100's, especially the TTSX with it's barn door bc of .357.

I shoot the 115 Ballistic Tip in mine almost exclusively and occasionally the 110 Accubond. Both are spectacular killers. The 257 just flat hammers game.

As an aside, if you have any RL-25 lying around, give it a go. It's by far, given the best results with 115-120 gr bullets in every 257 Wby I've owned.

wbyfan1...was wondering what you are getting for velocity with RL-25 and those bullets.

One of the reasons I'm looking at the 100 grain Swift Scricco is its .429 BC. The Accubond is .418. Most of the other bullets under 110 grains are in the .370-.395 area.

Bob,

With a 26 inch barrel, my pet load using RL-25 and the 115 Ballistic Tip usually chrono's right at 3400fps or just a skosh more. The load I use with the 110 AB typically runs a little over 3450. These numbers mimic factory ammo velocities. For what it's worth, I've discovered my best accuracy at or very close to max.

I've never tried the 100 Scricco, but a .429 BC would make them worth looking at, especially since they'd hold up well at higher velocities. I've had such good luck with the 115 BST, I just hate to waste powder and barrel life trying to find anything better. The 115, .257 caliber Ballistic Tip holds up better than most people think. For hunting whitetail, hogs, coyotes, etc.., they work wonderfully. If I were to go after large, thick skinned game, I'd look at something a little tougher though.

As posted above the 120 Speer with 70.0 grains of RL-25 is getting 3175 from the 26" barrel and .3 MOA. Didn't take 25 rounds to find the right load so I am a ways from burning out the barrel. Also nice is the trajectory of the load perfectly matches the drop circles in the Shepherd scope. Running the numbers the Swift should be close.

I am getting 3470 with the 110 accubonds over a Nosler book max charge of R-22. I have R-25 loaded but have not tried it yet.
