I'm thinking about a 257 weatherby magnum.
Who here shoots one and what do you like about it.
If you reload for it, what's your favorite bullet?
What animals have you shot with it?
Thanks

I don't know anything about them, but just to let you know there is one on consignment at Turners Rancho Cucamonga. Check their website.

I have a TCR 83 and one of the barrels is in 257 Weatherby Magnum. I haven't shot any animals with it, although those damn turkeys that walk downrange at Chabot are pressing their luck ......

I like it because it shoots fast and flat and recoil is fairly light, even in the "about 7 lb" T/C. I like that although 257 WBY brass isn't all that hard to find I can make it out of the easier to find 264 WM or 270 WBY. I tend to use IMR 4350 powder and the Sierra 90 grain and 120 grain BTHP. For whatever reason the 25 calibers tend to be a bit of a challenge for me but the 257 WBY did very well from the start.

I suppose that it's a bit of an exotic round that doesn't behave like an exotic round is a plus too.

I have one and really like it. I have shot pronghorns with it so far. Ranged from 50-600 yards and all one shot kills using Nosler 115gr Par bullets and IMR7828 with Fed215 primers.
The Fed 215 primers were originally made for weatherby cartridges.
I have some and am working on other loads using Swift 100 and 120gr A-Frame bullets as well as the Swift Scirocco bullets. I think they will be even better for hunting from my expierence in Africa with them. My daughter also shot a nice deer here with the 100gr Scirocco bullet.
I would use the 257Weatherby on elk with the 120gr A-Frame bullet.
I plan to use either the 100gr A-Frame or Scirocco for pronghorns next year in Wy if I do not use the 130gr Scirocco or 120gr A-Frame in my new 264Win mag.

I got some 270Weatherby brass that was reformed to 257Weatherby and had problems with it sticking in my rifle with loads that worked fine with the 257 brass.
I do have some load data if you are interested.

I have a 257 weatherby magnum reamer if anyone wants a gun rebarreled into a 257 weatherby...

It's just a badazz cartridge, but expensive for the non handloader. I have a few Weatherby's I think. If one cant find Weatheby brass regular 7mm brass can be utilized it just ends up with a little bit of a short neck yet results no issues.

Thanks fellas. I'm really leaning towards one. I load my own so getting tooled up for it will be easy. I'm looking to a antelope gun. I have an older 25/270 WC that shoots well but, she's purty and I'm not sure I wanna drag her through the mud.

I aquired a 7MM Fudrucker JGS finish reamer and sizing die reamer the same way.
Still waiting to wear it out.

Same lot had a 30-25wssm reamer.
Interesting little cartridge.
Like a 6ppc on steroids.

My father got a 257 weatherby this spring in anticipation of a wyoming antelope/deer hunt. He used it to kill a couple A zone bucks on opening day. It's a great hunting rifle that "shoots frickin laser beams".

He handloads but I don't know what he's using. I just know I about passed out when I saw how expensive factory loads were. Frankly, I want one now too. lol.

I have one but don't reload (yet).

It shoots fast and flat. At ranges under 350 yards, I can see the bullet hit the target before I heard the boom from the gun.

I use factory Weatherby ammo and my Vanguard likes 110 gr Accubond the best. You need a 26-inch barrel to bring the 257 WM to its full potential though. The 24-inch Vanguard loses about 200 fps.

toby
09-30-2013, 8:47 AM
The Vanguard only loses 100 fps with the 24" barrel people are getting 3500 easily. The 26" can achieve 3600 fps.

I had one years ago. It was a very expensive rifle to shoot compared to a 25/06

20 % more powder for 115fps was not worth the expense of the original cost of the rifle and keeping it fed.

56 grains of 4831 gets you 3287 fps out of a 25/06 and it takes 68 grains of 4831 to get 3361 fps out of the Weatherby with the same 100 grain bullet.

Take all the money you will save and buy a 25/06 that is really nice.

For accuracy the 26/06 wins hands down and will not eat barrels for lunch. Muzzle blast and recoil is way worse with the Weatherby.

Your weatherby quotes are way off. You should have used H1000 very easy to get 3600 fps well worth the effort and cost.

Toby, with all due respect, I took the info right out of the Speer reloading manual to make sure I was correct. Where did I go wrong ?.

toby
09-30-2013, 10:29 AM
Kevin the Speer book is the problem. They hold way back on loadings check Hodgdon, IMR, Sierra, Barnes, Nosler and make sure they up to date books.

Current manuals generally hold WAY back on charges.
What you want are 30-40yr old books...

Just doesn't change the facts. On a new 25/06 action not a sporterized old action you can still get a 25/06 to perform close to a Weatherby that shoots better at half the cost.

There is a reason it is a obscure caliber, it is a very inefficient case that erodes barrels. To each their own.

toby
09-30-2013, 11:45 AM
Show any data that produces any where near 3600 fps with a 100 grain bullet fired from a 25-06 even the AI version can't get it. Your looking at 3400 fps tops. If you dare go there, Big difference. I rest my case and you can ponder or stay with what you like.

KevinB
09-30-2013, 12:08 PM
Toby, 20 % more powder for 5 % more velocity. Plain and simple it is not a good efficient cartridge. The cost in recoil, muzzle blast and barrel life are just not worth it.

Divernhunter

I have both a 257Weatherby and a 25-06. Also have a 257Roberts. Where the Weatherby does much better is with 115-120gr bullets.

Yes it is worth it. Yes it is not as efficient just as most mags are not.

I got 2899FPS from my 257R and the best I did was 3000FPS from my 25-06 with 120gr A-Frames. So using your logic the 25-06 is not efficient and we should get the 257R. Less powder and only 100FPS less. This is over my Oehler Chrono.

Each cartridge has a usefull place.
I really like my 257Weatherby when hunting pronghorns or long range pig hunting that I have done. My daughter hunts everything with the 257R and everything has been a 1 shot dead animal.

I say it is your money and buy what you like.

Data: 257R--100gr bullet
48gr--3228FPS
43gr--3053
39gr--3021
49gr--3059
49.2gr--3186

47.5gr--2899-mag primers
47.5gr--2876-Reg primers
47.5--2916--Same powder different bullet

25-06--100gr bullet
61gr--3300FPS
51gr--3275
56gr IMR4831--3431FPS--Nosler PAR
47gr--3268
57gr--3395
57gr--3399
52.5gr--3333
54gr IMR4831--3300 Poot accuracy

Cant argue with that logic. My wife shoots a 257 Roberts, great gun, easy to shoot and it will last forever. Shoot that Wheatherby a couple thousand rounds and you will be hanging a new barrel on it.

One of the issues I have with the Roberts is it is impossible to find factory ammo for it, same issue with the Weatherby.

The original poster asked about the Weatherby and I gave him my opinion based on my own experience.

I hunt Yotes a lot. My go to long range gun is a 26/06 that has several thousand rounds thru it and still shoots a half inch if I do my part.

There is no right or wrong answer here, just supposition on everyone's part.

Says you. The thread is about the 257 Weatherby and YOU brought the 25-06 argument in to the works, then changed velocity to efficiency then you brought in erosion and barrel wear along with cost and also stated the 257 was an obsolete cartridge, guess what it's Weatherbys 2nd or 3rd best selling caliber and growing by the day and you still think that 300 fps means nadda. Haters will always hate I guess. ps I shoot a 250 savage, 250 savage imp, and now a 25-284 and a 257 weatherby I own no 25-06 yet but it will be an IMP as well and I never cared for the Bob version. So I think I have the Quarter bores covered on what they can and will do but thanks for the input, I'll consider what you added here as filed. Good shooting

KevinB

Toby, "says you" is just a argument. Obscure is not obsolete. Not sure where you got that. Barrel wear and erosion has always been a problem with Weatherbys. My own 257 Weatherby had erosion problems at 1200 rounds. The math with the powder charge is correct. The recoil and muzzle blast is correct.

By your signature we can see that you are a big Weatherby guy. I don't have any sales numbers but it would be my guess that there is 1000 26/06 rifles sold per every 257 Weatherby sold. The reason for that are all the reasons I have posted.

My go to long range gun is a 26/06 that has several thousand rounds thru it and still shoots a half inch if I do my part.

Most people just call those a 6.5-06.

I've never owned one or even shot one.

But, I acquired some reloading 'stuff' a few years back including a set of RCBS Competition dies for it -- the ones in the wood box.
I'm thinking about a 257 weatherby magnum.
Who here shoots one and what do you like about it.
If you reload for it, what's your favorite bullet?
What animals have you shot with it?

Most people just call those a 6.5-06.

And that would be caused by a lack of proof reading. 25/06 is what I should have written. I did have a 6mm/06 built once, it was not a good choice.

There is a difference between a standard wa;nut stock and a blonde birds eye maple stock on the 25/270. Easier to find a Remington 700 stock than the Wildcat. Will probably put a B&C on the Weatehrby anyway.

KevinB - Not everyone is concerned with wearing out a weatherby barrel. It sounds like you get to shoot a ton which is a great thing. For those of us who don't or have many rifles to spread the love around the probability of wearing out a barrel is nill.

Why? Was it rifle or round? I love my 6.5 swede and I can only imagine what an '06 case could do for 6.5mm bullets.

KevinB
10-02-2013, 6:31 PM
It really didn't excel at anything. It didn't shoot lighter bullet great and or heavier great. Wasn't the rifle, McMillan barrel, FN action, great rifle builder. It just wasn't a great rifle.

I sold it to a hunting buddy that still shoots it a bunch. I will say whatever he points the rifle at it dies. Then again he is a great shot. Many a yote has met death with that rifle.
