I have an AR15 upper made by ATI (American Tactical Imports) and I'm having difficulties finding ammo that will feed properly.
I finally broke down and purchased the ATI brand ammo ("specifically designed for use in the ATI .410 bore upper)
The new ATI ammo seems to have a difficulty holding onto the primer after firing.
I fired 10 rounds, and had 3 failures to feed due to a primer that blew out of the shell and fouled the chamber.
Is this just inferior ammo, or could it be a head-space problem?
