I just ordered a 6mm Creed Ruger American Predator. I intend to use 55 grain Nosler BT's and 65 grain V-max. I am concerned about bullet blow up.
Book velocities on the IMR 4064 I intend to use show 3900 fps on the 55grain and 3750 fps on the 65 grain. Those would be from an 8 twist barrel.
The rough formula on rotation, (MV*720/TR) shows 351,000 rpm on the 55 and
337,500 rpm on the 65.
Will those bullets likely take that or will I be trimming down the velocity?
