Good point. You hear about guys having issues with loose primer pockets in the FC 223 brass, where I have never seen it. Wondering if those guys reamed the pockets, where I swage them???
I've had loose primer pockets in Federal 223 brass from factory loaded ammunition, no primer crimp or removal involved.
I've also reamed the crimps out of quite a large number of LC 223/5.56 cases and never had a loose primer pocket in those.
