I recently purchased AutoComp as I could not find Accurate #7 that I had been using and I wanted powder that I could use for 380 ACP as well as 9MM. For 9MM I am using Berry's plated 115gn RN bullets, WSP primers. Berry's says to use lead data. My lee handbook as well as the Hornady web site says that the load should be 4.4 - 5.1gn with COL 1.140 for lead round nose. I first tested 4.6gn AutoComp, COL 1.14 - my Glock 19 failed to cycle and the shells landed right next to me. Next I tried 5.0gn AutoComp, COL 1.14 - the Glock cycled but the shells were badly scorched down the length of the shell. Next I tried 5.5gn AutoComp, COL 1.13 - these worked fine, but I am over the recommended load for LRN bullets. The Nosler site shows 4.5 - 5.5 COL 1.1 for 115gn JHP and the Hornady site shows 5.1 - 5.6 COL 1.25 for 115gn GDHP. Should I worry about using 5.5gn AutoComp? Am I going about this correctly?
