[QUOTE="yorke-1, post: 1792146, member: 11960"] Having a shoulder angle that's too sharp can cause problems with some powders; powder bridging is a very real issue if you're trying to burn something like H50bmg in a 6.5mm with a 40° shoulder. The sharp shoulder angle can cause extruded powders to form a "log jam" at the case neck and give some pretty extreme pressure spikes. A 35° shoulder angle doesn't have that issue. [/QUOTE]
