Don't know if you're the only one, but I've never had any trouble priming GFL brass. Usually it's the military brass (FC, IMI, WCC) with the crimped primers that make re-priming difficult, unless you remove the primer crimp ring.GFL Brass has given me nothing but problems trying to insert primers. I find it possible to get them in, but not without a fight!! I'm surprised that nobody has mentioned that. Am I the only one??
