"...5 cases out of 17 in one box of factory ammo that the punch that forms the primer pocket did not go to the bottom of said pocket, more like half way. " "...they all functioned perfectly out of my Remington 7400 ..."
Well, I'm still puzzled. Are you saying Remington made and loaded a box of ammo, the primers were all in place, they all fired perfectly but you are now finding the primer pockets of five are only 'half way" formed and the bottiom didn't go to the bottom? That just don't seem possible, what am I missing?
And, what would you hope Remington might do?
