Well, my Starline brass came today. Went to Gander and they only had AA#7. So, for those who know, I was thinkn bout staring at 10gr and go'n up by .2 till I got 1200FPS. What OAL should I start with? 1.25? This will be out of a G20, CCI300 primers, stainless guiderod, 22lb spring and a LWD 5" barrel.Whats the thought on #7 for 200grs? Pros and cons of #7? What say Ye? Thanks,E. Wanna kill these ads? We can help!
