[QUOTE="gr8whyt, post: 473304, member: 28526"] This is something that's interested me for a while. I think most gunsmiths recommend an 11 degree target crown. Is 11 better that 10 or 12 degrees? Somebody must have done tons of research to determine that was the best angle for bullet and gas release. Yet the factories don't do this. Why? Must be cheaper to just put that bubble thing on there. Then when gunsmiths put a brake on the muzzle, gas goes every-which-way. So most agree that crowning is not critical and just make a 90 degree cut. Strange. Personally I think that as long as the crown is perfectly perpendicular to the bore, and free of burrs or damage, the shape of the crown really doesn't make much difference. But I've been wrong about less important stuff before. -- gr8whyt [/QUOTE]
