You'd need a water cooling jacket built around that one!
He could at least give you 3 peices for dummy rounds to get a reamer made lolI didn't even think of that but now it's on the brain too dang it. My buddy even has a 28 Nosler…perhaps some of his brass needs to be donated for "science"
That aint no lie!You'd need a water cooling jacket built around that one!
Hmmm.Hey all, I have a barrel I want to build with, not now but in the next few years. Originally I was going to go full throttle and pursue the highest velocity possible just for fun, no practicality needed.
It's a 32 inch bartlein .257 1:10 twist very heavy barrel, and is presently chambered in 25-06AI. Throat is in good shape at present.
I was originally going to build either a 25-300 wby, 257 stw, or even a 25-300 RUM off of it, leaning mostly towards the .25-300 wby for a few reasons, Peterson making 300 wby and 6.5-300 wby brass among the greatest reasons but also I already have 257 wby dies for the neck sizing portion of this and 450 ackley dies that with the decapper expander unit removed should do just fine to resize the body. And with the lightweights that the 1;10 twist is limited to I have serious doubts that even out of a 32 inch pipe the RUM capacity would meaningfully outrun the full length wby or stw case but I could be wrong. It's already threaded for a savage action which I have. And if I went full length magnum it'd clean up the existing chamber completely without any need to set back or rethread the beast.
But now I'm second guessing this too…
I already have a 257 wby and a pile of brass for it…and I'm sure that out of a 32 inch barrel the .257 would already be STUPID FAST, perhaps there's not much to be had going bigger than that, again with a 10 twist and the bullets were limited to here. If I could shoot the 130+ grain bullets it would be different. I would have to have the barrel set back and rethreaded I think though based on my studying of case dimensions/chamber prints.
I'm also reluctantly considering just leaving it alone as the 25-06 AI that it is except inexpensive dies for that chambering seem to not exist or be hard to find so that's the downside, I'd also need to obtain brass and fire form it which kinda lessens its appeal regarding longer barrel life if I'm using that life to fire form cases too. But maybe that's a non-issue, I've never actually had to fire form before, no experience yet with builds or wildcats. But I do imagine that a 32 inch .25-06 ai would likely outrun my current 24 inch .257 weatherby, possibly by a bit.
Anyway, what would YOU do if you wanted a .25 cal speed demon on a bit of of a budget with the supplies on hand I've mentioned? Leave it as a .25-06AI, set back and rechamber to .257 weatherby on account of existing supplies and that round being about the practical top end, or just listen to your heart and go flat out with a full length magnum overbore monstrosity to take full advantage of the 32 inch barrel length and see just how fast we can go, barrel life be damned….it is a long enough barrel that a person could easily set it back quite a few inches after the first 500 rounds or so if need be.
Input please, and as always I just like talking about all this stuff with you people so do chime in!
@Fiftydriver you're about the foremost authority on big 25s in my opinion, again IF LIMITED TO A 10 TWIST what route would you suggest?
A former pastor of mine always said if it's worth saying it's worth repeating!!!Why not go with the 257 STW? Cheaper brass than the others, and with that 32" barrel you might be able to use the heavies like the 130gr. range of bullets.
