[QUOTE="Trickymissfit, post: 733070, member: 25383"] honestly for black bear and deer (I used to live near Lawton) the .257 Roberts would work fine with proper bullet selection, but I think the sevens would be a tad better. The 57mm case length dosn't work well in a Remington short action even though they've chambered it from time t time. OK with light and short bullets but not those 117 grain ones. A Savage is a little longer (about .150") and ought to work fine. But none of the 30-06 case lengths will work in the short actions. You must havea long action. The 7x57AI is Ackley's best improved round (he said that more than once). It will give you ballistics right up there with a .280 Remington out of a mid sized case length. Has the desired longer neck and sharp shoulder angle. Barrel ought to be good for at least 2,000 rounds. Fire form cases by firing factory 7x57 rounds thru the barrel. What you'll end up with in the end is a .257 Ackley necked up to 7mm. Of course you could simply chamber a 6.5/.284, but I'd rather have the smaller diameter case. The samething could be said about the 6.5AI round as well, I might add. gary [/QUOTE]
