250 Savage twist rate question

Am toying with idea of rebarreling what I think is a model 1910 Remington rolling block chambered in 7x57 mauser....bore is decent, chamber a problem.

Anyway, noticed Green Mountain makes a rolling block octagon 30" barrel with 257 bore. Figure chambering it in 250 Savage cartridge would keep the pressure within strenght of action.

However, the Green Mountain barrel has a 1:8 twist and just wondering what grain bullets would be appropriate for this twist rate. Mind you I don't hunt, just shoot paper.

With that twist it should shoot all the normal weight bullets for the 25 caliber.

As long as you let me shoot it, you caan chamber it in anything you want.

Since you aready have so many "Bobs", take a walk on the wid side!

JTEX, LOL, if Kris had a 250 Savage reamer, the rifle Sunday would have been one. We're talking going in together on the reamer...he wants one too.

I recall reading an article by John Barsness where he stated that the 250 Savage should benefit from a twist faster than the now standard 1:10". This mainly applies to bullets of 100 grains or more, or bullets with long bearing surfaces, where the 250 savage (and the 257 Roberts to some extent) does not drive the bullet fast enough to stabilize them. With such a long barrel, you would probably have such a large velocity gain that a standard twist barrel would stabilize the long heavy bullets just fine. You may find that the 1:8" twist gets those 117gr SST and 110 Accubonds to shoot very well. I doubt a fast twist could hurt accuracy with lighter bullets. I would just try it and see. Here is just a thought, and I don't know if it would really be necessary, but you might want to ask your smith if there would be any benefit in bushing the firing pin and heat treating/hardening the action. Good luck.

FISH!!

Heed the words of Winston Smith in Orwell's 1984:

"Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right."
