I started loading 9mm Luger recently and have been having some problems. I started with Hornady 115 grain round nosed jacketed bullets, before I progress to some lead projectiles that I have purchased before buying a mold. Using random make brass I am shooting them in a Norinco Model 213. Winchester factory 115 grain round nose bullets shoot just fine. I have tried two powders and both of them had the same results. W-231 powder at 4.2 grains over a Remington 1-1/2 small pistol primer fire ok for me, but the limp-wristed can't get them to cycle properly. If I increase the powder a few tenths of a grain, the primers show flattening. So, I tried a slower powder, 4.5 grains of Unique with the same result. Varying the powder a little gives me either improper cycling of the gun, or flattened primer with no firing pin dent showing. So, should I try even slower powders or faster powders?
