[QUOTE="ntsqd, post: 2692688, member: 93138"] I did use Berger's stability calculator, but my velocity numbers weren't correct. Been so long ago now that I don't recall where I got them from. Put me into a twist (8R) that I don't think this chamber can drive the heavies fast enough for, and as I understand things it isn't going to be real friendly to the light to mid-weights. I'm re-thinking this whole project anyway. I suspect that 140's are the heaviest this barrel would see in the current chambering. Am thinking to order another 7-08 barrel twisted for 120's-140's and re-chamber this one to 7SS for the project rifle that will come after this one and a .243AI build. Yep, I do realize the bolt face difference. It's for a Savage, so it's not too a big deal. [/QUOTE]
