[QUOTE="AZShooter, post: 1274919, member: 5219"] John Barsness, the gun author, said you will get a velocity increase that is 1/4 of the difference in case capacities. The 6mm Rem has a case capacity of 54.9, the improved has a capacity of 60 54.9 divided by 60 = .915 subtract .915 from 1 equals .085 increase in case capacity divide by four is .021 take any velocity you get with the standard case and multiply by 1.021 Some handloaders may report higher velocities than was computed. I would suggest they are running at higher pressures. --------------- links on the subject: [url]http://www.longrangehunting.com/forums/f17/6mm-remington-vs-6mm-ackley-76156/[/url] [url=http://forum.accurateshooter.com/threads/6mm-rem-vs-6mm-rem-ai.3773296/]6mm Rem vs 6mm Rem AI | Shooters' Forum[/url] [/QUOTE]
