Are you short on cases? Might be able to salvage those by annealing the necks and running them back through the sizer die. Back the ie out run ram to top of stroke the turn the die until it contacts shoulder, then adjust down till the bulge is gone. Only have to make it chamber in your rifle, it's OK if it looks a little funny it will fire form back into shape on its next firing.
I have some severely dented 5.56 cases that I'm processing right now that look terrible a couple were almost completely flat that mostly went back into shape. Should have taken pics.
If you dint know what annealing is or how to do it there are videos, different types of machines, that will process a lot in a short time frame, but I use a plumbers propane torch, touch yhe flame on the neck shoulder junction for about 30 seconds hile rotating case in the flame you can watch the heat ring move down past the shoulder. Let it extend a short distance past the shoulder and then let it cool off. Hold the base of the case with an oven mit to avoid burns on your fingers and DONT EVER heat a case with a live primerin it, it will detonate. Ask me how I know.
