AirPowerCould you measure that ammo for diameter right at the widest driving band?
Airpower.... Do you have a length for the 64.5 gr. bullet?....Bob
Sounds promising, as we can get a 1 in 14" twist in 0.224".... Here is a stability chart for that, using a bullet that is 0.472" long....The stability is 1.5 at 1050 fps, increasing to 2.0 at 900 fps.... The bullet would be stable (>1.0) even at the speed of sound in a 14" twist....Bob
