OhioGlockMan, after I started re-reading everything and looking at other empirical data, I realized that might be pretty hot. I don't have any Blue Dot, that was why I was looking at the Unique, and AA#7. I don't use the 180gr slugs in .40 any more, since I don't like the round, I wanted to use what I had for now, and get some experience loading 10mm loads. I may get some blue dot and work some of that up. I never cared for the Unique in my .45, just seems really dirty. I only have a stock Glock 20 barrel for now. Does anyone make a fully supported barrel for the Glock?
