Tight primers in .223/5.56

Recently obtained a Hornady LNL progressive press. Not too shabby, but seating primers is probably the weak link with this design. I've always used a hand priming tool because you can "feel" the seating better, and with tight fits you can usually get the job done. I just tried loading my first batch of .223 on this and had all kinds of problems seating primers in some tight military cases.
Now, before you jump to the crimp issue, all these cases were deprimed and then run through the RCBS tool that swages out the military crimp. While I read up and discovered Lake City and other .223 might need to be "uniformed" because their pockets are too shallow, that's not my problem - it's too tight of pockets to begin with.
Anyone have any ideas on how to address this? I would think someone makes a cutter that uniforms the depth, removes crimps, and also uniforms the width......????
Thanks for your input!

I find chamfering the pocket with a countersink tool mounted in a 3/8" drive variable speed drill to be much faster. Still, some cases have a tight pocket and you have to wince and force the primer in.
Maybe the Dillon 600 would do a better job of swaging the entire pocket?
