I have a .223 AR-15 and when I resize my fired cases, any that need to be trimmed come off the Lyman electric trimmer without a problem.
My neighbor has a ".223" but when I resize his cases and try to trim them, I cannot pull them off the pilot without stopping the unit and using a screwdriver against the pilot holder to prevent the whole works from coming out the the trimmer. The only way I can successfully trim them is to partially trim, then deburr in and out of the case mouth, then trim again.
If he really has a 5.56mm and not a .223, might that be the problem? If not, what is?
