[QUOTE="Trickymissfit, post: 719771, member: 25383"] Ackley never did a 7-08AI for starters. But it's also pretty must a waste of time as you won't gain much of anything by improving the case except to stop brass flow. Where as a 7x57AI will pretty much push a 140 grain bullet to about 3200fps with nearly double the barrel life of the other. There's also the 7mm Arch which is pretty much a 6.5x55AI. That one's good for nearly 3100fps as well. Nice thing about the Arch is that you can form the cases out of generic .257 Roberts brass to help make up for the case shrinkage during fire forming. The neck's already too short in the 7-08 before you improve it, and it will shrink that number another .03" when it's done. Meaning a rather dismall barrel life gary [/QUOTE]
