I have reloaded for a few years, recently I loaded 100 rounds X3 fired brass. 3 of the rounds out of 100 the primer seated with very little pressure and seated very easily compared to the rest. Should I be tossing these now or after the rounds are fired again? The primers are WLRM and the brass is Federal. The primers are not moving or falling out they just seem to go in like there was no resistance at all. I am shooting close to max load but .5g lower than advertised data. Zero pressure signs on the brass.
