[QUOTE="J E Custom, post: 1356252, member: 2736"] As stated before, .062 shoulder is more than enough because the barrel torque is no where near enough to upset the shoulder if both surfaces are square. If you think about it when using the barrel nut you only have the height of the threads acting as a shoulder (They are far less than .062 and are on a 30o angle and tend to climb each other). A shoulder of only .030 would even be better than the thread because the square surfaces done want to climb and the effective surface is as much or more. Another advantage to using a shouldered barrel, is more wall thickness around the cartridge. thicker shank diameters expand less during firing and this makes extraction easier on high pressure loads.
