I haven't had any primers jarring loose, but I've given up entirely on Critical Defense ammo.
I took a batch [.40 S&W] to the range with some buddies a while back and we had constant failures to feed with three or four different handguns we were shooting.
The pistols would feed everything else we shot, including our basement handloads, but at least one or two rounds per box of the CD would hang up on the ramp.
If it were just one pistol, or if the problem occurred with multiple types of ammo I'd be more skeptical, but three pistols with multiple failures using Critical Defense and zero failures using any other of the half dozen different kinds of ammo we had, indicates to me that the problem lies with Hornady, not with the pistols or the shooters.
