It seems like I've been seeing a lot more dud centerfire in the past 10-12 years from domestic producers. It's odd that I can only recall a few bad primers on new production imports and I've shot a ton of the steel crap 9, mak, 223, x39, and 45. That's not to say some of that stuff didn't have other issues with cycling or soft rims, but less than a handful didn't go bang. I cannot say that about the current winchester and remington bulk. At least 1 or 2 duds per hundred lately and plenty of mis-loaded (bullets backwards, stuffed too deep, folded case mouth). Given bulk is cheaper and occasional junk is part of the game I can sort of live with that, but any duds from a premium ammo would be extremely disappointing. That should be subject to better QC given the price and expected end-users.
