I rely almost exclusively on Federal for my commercial ammo needs so was surprised in shooting up the tail end of a case I bought roughly a year ago to find a primer neatly inverted (anvil exposed) in this factory ammo.  Never seen such a thing in anything except my own clumsy reloads.  Otherwise fine albeit mildly loaded ammo; holds about 2.5 inches at 100 yards in my M4 Bushie 14.5/1.5" brake barrel.
