[QUOTE="lynn, post: 35728, member: 1479"] Winmagman You need the boattail to bearing surface length 0.050 in front of the neck shoulder junction in your cases to reach both peak accuracy and muzzle velocity.Seat a bullet to this setting and measure your overall length then chamber the round and measure your overall length on the same bullet.This will tell you how much longer your throat needs to be cut.By chasing the throat you'll never get good accuracy or velocity out of your existing barrel.
