I have never had a primer that was hard to seat. I had some military brass that had Berdian primers that had two flash holes off to the side with no hole in the center.
The only reason I can figure they did that was to prevent them from being reloaded.
I made a drill bit extension and ran a .075 dia bit right through the center of the brass.
Used the primer unseating tool and knocked it out. Then I find out that the brass was swaged around the primer cup. I borrowed a sizer for the primer and finished off the 20 I had drilled. took the rest of the 500 and turned them in for recycling.
I did not reload the milbrass after that.
