When I reload ammo for matches I always use a case gauge and check every loaded round for primer problems, case length issues, and sizing issues. It has saved me from disaster on more than one occasion. When case gauging, I’ve often found a cartridge with an upside down primer, or one with a crimp or bulge that would have prevented proper chambering or extraction during the match. When I practice, something I don’t do often enough, I don’t bother.
