TotT,
do you use a copper remover bore cleaner? another thought... have you ever trimmed your brass? if the case overall length gets too long after several reload cycles the case mouth will drive into the throat leade and crimp into the bullet. this could cause your hard extractions as of late where factory ammoi is fine. if you're not seeing rifling leade marks on the bullet, check your case length. i suspect the case mouth is getting pinched into the bullet at the end of the chamber. or that is a possibility. trim that brass length. or at least check it.
