[QUOTE="Trickymissfit, post: 491064, member: 25383"] I wouldn't buld a 222mag (what a .224/.204 really is). What I would build would be a .223AI, but with the .222mag neck design. The longer neck will handle longer bullets better. There is very little difference between a .222mag and a generic .223, but with the longer neck you can keep the bullet outside of the body of the case. Tobe exact, there's little to be gained with the Ackley chamber over the standard. I'd find a nice .222mag reamer and ream it so a .223 will headspace correctly on a go gauge. But if you could get a reamer ground to the Ackley spec and .222mag deminsions, you might see a hundred fifty feet per second increase in velocity. You could also build a .224BG by ordering in a new bolt & reamer from Dave Kiff. The case at the shoulder is 1.352 with minimum taper. The neck is about .35 with a 30 degree shoulder. This ought to push an 80 grain bullet out to 2850fps if not 2950fps gary [/QUOTE]
