[QUOTE="groper, post: 473490, member: 12550"] Nice... Id hazard a guess and say the AL tipped ones would stabilize from a 1:9twist thanks to the reduced transverse moment of inertia. The increased fineness ratio of the nose also moves the center of pressure aft aswell... The bronze tips, would probably need the full 1:8 or maybe 8.5twist... I was looking at making some high BC bullets in 30cal, but noone seemed to have the barrels to shoot them... maybe this will catch on and a few more people will order some faster twist barrels for the big 30`s...?
