Mod\'ing a Savage 12BVSS .223 to .22-250 AI Heavy
Ok. This is something that I *think* I saw on a shooting board somewhere in the last week (then again, it could just be the voices in my head. What was that, again?) Someone was grumbling (as I have) about the relatively slow rate of twist in most factory .22-250 barrels. Upon subsequent modification to .22-250 AI, they still have a slow twist, which doesn't do any good if the object is to push heavy bullets at moderately fast speeds.
One possible solution was to obtain a Savage 12BVSS in .223 Rem, which has a twist of something like 1-9", then change out the 'head' of the bolt to one of suitable size for a .22-250, and then have the barrel reamed to .22-250 AI, and Voila! a .22-250 Ackley Improved w/ a fast twist, for a budget-friendly price!
I'm not entirely familiar w/ these guns construction; is the bolt part correct/feasible? Hell, is the whole idea workable? Anyone see potential pitfalls that I should watch out for?
