[QUOTE="Chamberman, post: 2381831, member: 45142"] An 11 degree crown with a 60 degree centering recess is optimal, or an 11 degree alone will work just fine. The biggest thing in my opinion, is that whoever does the work needs to polish the muzzle to 800 or 1000 grit and final it with some type of polish like Flitz. This helps to dissuade the carbon and makes for easier cleaning of the muzzle when using a brake or suppressor. Remember- the crown is the last thing a bullet touches as it leaves the barrel, so it needs to be sharp! No dings or galling. It is VERY surprising how important this is. [/QUOTE]
