I load everything with my Lee 45 ACP dies, including the dreaded A-merc stuff. The FC die woks it's magic and they all shoot. I have many rounds of PMC brass because the range where we shoot used to sell it as there range ammo new stuff. Never had a problem with Lee resizing/de-capping.
I have had one case kick the de-capper pin up into the collet--it was a Federal nickle plated case--primer hole was slightly off-center.
