257 Weatherby?

Have been thinking about getting a 257 Weatherby. What does everyone think of this caliber? Also is the extra money worth the Mark V for the 26 inch barrel or is the Vangard 2 with the 24 inch barrel sufficient?

Had one since 2008, so 6 years now. Great caliber....But my .25-06 AI can do everything my .257 Wby can, wtih 10 grains less powder, cheaper brass, and alot less recoil, and muzzle blast.

Velocities are even the same pusing the same weight bullets. It's the damndest thing I've ever seen.

There is a theory called, The Point of Dimishing Returns. That basically states that a caliber reaches it's full potential at x-sized case with minimal negatives. But you can get more velocity using a larger case, but it's gonna have several negative effects, like worse barrel life, using significantly more powder, more muzzle blast, more recoil, etc...

So, in my opinion, based on my experiences with both calibers, I would have to theorize that the '06 sized case, is about the maximum case size (efficiency wise), for the .257 caliber bullet. I think anything more than the .25-06 AI, is where you start getting into diminishing returns, just to reach nearly the same end-result.

I still recomend a 26" barrel for either caliber you choose.

I shoot one as well a MarkV 26" barrel, the 26" will get approx 3600fps +/- the 24" will do 3500fps+/- the 25-06 AI is pressed and pressured real hard to achieve what the Weatherby's will do and hey their true Weatherby.

How are you getting 3,600 fps out of a .257 Wby? You must be shooting some light bullets.

I only shoot 110 Accubonds or 115 Bergers. Around 3,300 fps out of both.

And yes, that's pressing the .25-06 AI, but it's also pressing the .257 Wby. Because I'm getting the same velocities with only 60gr of 7828 SSC in the .25-06 AI, as I am with 70-71gr of H1000 in the .257 Wby.

I have a "true Weatherby" and it's barely a 1 MOA gun on a good day. It's a friggin Mark V Accumark, and it has so many tight-spots in the barrel from the factory, it's a joke...

Won't ever buy another Weatherby, if they can't make a $2,200 rifle without major flaws in it...

Re: 257 Weatherby?

71, mine is a Vanguard with a 24" barrel. Timney trigger, re-crowned muzzle, B&C Medalist stock and had the barrel cryogenic treated. Using Berger 115 VLD's and Mudrunner's H1000 shooting .630 at 200. Got it new for a ridiculous low price and have made a little project out of it. I hunt Javelina with it and enjoy it. The most accurate load is not the fastest velocity. Bet the Mark V with the 26" barrel would perform better. Buy the rifle you are happy with and good shooting.

Re: 257 Weatherby?

I am biased on many things in the rifle and accuracy world, Weatherby is very hard to beat and can not be out done by any out of the box rifle. Most of the cartridges are better than many of the wildcats. However the efficiency of the 257 with todays components compared to the 25 06 is not as much as one would think. A non Ackley, non improved, 25 06 loaded with a 100 gr ttsx, Pushed by a max load of rl 25 and a mag primer will impress you to no end. Free bore it to the max in a 26 tube and watch the chrono go to 3650.. NO SH!T

On a side note the ttsx really likes to be pushed hard. This bullet will out perform all competitors bullets up to and including the 120 gr class. It will out penetrate, out kill and the hydrostatic shock is phenomenal. Shoots flatter too.

Mud. Fire lap that barrel. There was a production run of Criterions that did not come out so good. You have one.

I never knew they had a bad run....You would have thought they would have ran a jag through the bore of a $2,200 hand-built rifle before it left the custo shop....

That's good info, though. Thank you for that.

My smith checked it out and said it looked like a bunch of midgets used pickaxes to rifle it. Said it was THE worst Weatherby barrel he's ever seen, even Vanguards.

So, his suggestion was to call Wby. I would call them, but I want to build a wildcat 6.5, that I have already designed. But I want to use an Accumark barrel blank (since it IS an Accumark already), but I don't think they offer anything in a 6.5mm option, do they?
