[QUOTE="4ked Horn, post: 56908, member: 11"] [ QUOTE ] What is a .280 ackley, a calibur or is Ackley a rifle brand? [/ QUOTE ] Once upon a time there was a man named P.O. Ackley and his passion was to modify existing cartridges to improve their performance. His standard operating procedure was to remove most of the taper from a cartridge wall and to lift the shoulder angle. This would serve several purposes. It would increase case capacity in terms of volume, it would reduce rearward thrust against the boltface and since he based his improvements on some of the existing case dimensions it would allow the shooter to fire form the brass simply by shooting factory ammo in the new chamber. Since his rounds were based on existing rounds they were not really a "wildcat" round. They were "Improved" so we end up with a 30-06 Ackley Improved or 30-06 AI and so on down the line. If I'm not mistaken he used the same wall taper and shoulder angle on all the rounds so even now that he is no longer with us we can still make these changes and still call them AI.
