603 , I have been reloading under that same assumption myself for many years . Is it a fact that you regain some velocity by using powders with a faster burn rate ? One thing is for sure , it really cuts down on the fireball that exits the muzzle . As I understand it , that fire ball is Powder burning outside of the barrel . Ergo my thinking is Faster Powder burns more completely thus having a better chance of obtaining top velocity for that Barrel length ! Of course my thinking can be flawed occasionaly !
