As harsh as ol Big Stick is...he's 100% right in the .223/.223 AI recommendation, also about brass. If the OP is worried about 500 pieces of brass then a .223 is hard to beat.
Stick, have you shot any game with the 90gr A-tips yet? I've been considering them for a 22-243.
How fast would you need to spin those, what twist?
