[QUOTE="Trickymissfit, post: 698911, member: 25383"] if 28% amonia won't remove the copper after three or four minutes of soak, it's pretty much welded in place. The throats go fast because the vortex of the flame pathe is right at the tip of the neck. A 40 degree shoulder would do wonders in barrel life, but pushing the shoulder back .075" with a 40 degree shoulder ought to give you a solid thousand rounds of bore life, if not even more. I doubt you'll see 50fps loss in velocity as the case is already in an overbore condition. gary [/QUOTE]
