[QUOTE="Len Backus, post: 30141, member: 1"] Meichele I have heard the theory of faster velocities with slower twist barrels. I wonder if anyone has an informed opinion of how much difference this can make? Let's start with a base muzzle velocity of 3400 with a 9 twist. How much slower would the higher pressures of an 8 twist barrel cause the velocity to be if loaded to the same pressure as in the 9 twist barrel? [/QUOTE]
