No, it did not stick. It would not close over the rim. Again, this is a brand new rifle. It appears that military ammo is loaded to a lot higher pressure, and an inspection of the case shows that there may be some gas leaking from the primer pocket, a sure sign of excessive pressure. The primer is not flattened out, but military primers are a lot thicker so pressures may not show up there. I did get the case out, with a cleaning rod. It wasn't stuck, it fell right out when the rod hit it. I think I'll stay away from GI ammo and only use the brass.
