What is the minimum diameter threading to go for a rifle muzzle when rethreading. I wanted to go to 1/2 x 28 tpi, but was told it doesn't leave enough meat around the .308 bore. Any help ?? Anyone have experience in this area ? Have seen some gun makers go this small on a .308 but usually only find it on a .223
