How many rds you get out of your brass depends how hard you drive it. I am on my twelth loading on Rem brass, 300 SMK, 105 gr US869, vel 2830, ES single digits. I ordered some from Midway at 42.00/100 and found 3 bags of 100 at my local pawn shop for 32/100. I reckon he had them for a while, anyway that will be enough to wear out a couple of barrels. By the way I love the Edge, it may be the biggest bang for your bucks and it goes WHACK when you hit something with it. Also its no slouch in the accuracy dept. I shot a 4.108 at 1022yds from a harris bi-pod and a sock.
