I have a 257 Weatherby Mark V with a barrel that's toast. I'm planning on rebarreling the gun and struggling on what to do with it. Could do the 257 again with a faster twist barrel. Half tempted to do a wildcat 6.5-257. I like the 257 because its easy to shoot and crazy lethal, but wouldn't mind a slightly heavier bullet. I already have all the dies for the 257, so if I change the bushing, the 6.5 is an easy option.

Already have great hunting rifles in 338 edge, 300 WM, 308, and 45 raptor.

What would you guys do?

Fast-twist .257 Wby for the 131 Blackjacks, or 1:8 twist 7mm RemMag.

I agree. Look at the Blackjack Bullets 131gr. They have barrels/bullets on their website.

More 25 cal bullets coming? I saw the blackjack, but it's a match bullet and the hunting line is still to come.
Im just wondering if is more advantageous to add .007 bore diameter to have 105 -156 grain bullets.
The most I'd do is .277 because I already have the big hitters

I think your idea of a 6.5-300 Wby is a good one.

With all the great bullets and readily available barrels. What's there not to like?

Had no plans for a 6.5-300. Was simply considering a 6.5-257. But if I can get something about 130 grains for hunting in a quarter bore, then I'll keep the regular 257 bee.

MY BAD... Meant to say 6.5-257. IMO The 300 case is way too over capacity for a 6.5 LR hunting rifle.

The 84 grains of case capacity for the 257 Wby should be perfect for loads using VV570, Re33 or LRT powders. I would think that a 26" barrel should get you over 3200fps pushing those 156 gr. pills.

Re barrel it in 1-7 twist then you can use the 131 blackjack ace. Or the 128 or 121 hammer bullet. If you wanna sell it might be interested.

I've set up a 6.5-257 which was assembled by McWhorter. My business/hunting partner bought it used, and ended up having McW rebarrel it because the original barrel was toast.

I tweaked their recipe, and he is shooting the 140 Berger at 3300fps with 70.5gr of H-1000.

This is exactly what I would do. Just a hair faster than a 264 WM, and since the op already has brass and dies for a .257, seems like a no brainer. In hindsight, I wish I would have kept my .257 Ultra Light and did the 6.5 conversion on it, instead of selling it when the barrel was toast.

I'm the new guy so guess I'll be the odd man out. Just rebarrel it as a 257 Wby but I'm very partial to the caliber for deer and pronghorn. It is the devil you know.
