I've used BD in the past 20 yrs for 45 & some magnum loads. I am new to 38 Super - age = bad eyes = RED DOT!! I am loving this gun. It was made by Cameron Custom here in Phoenix AZ. I have tried AutoComp which works very well. 3N38 was OK, same grains as the BD (almost) to make Major, 10.5 = 171PF. 7625 made my Dot dip & wobble a bit. Tried AA7, dirty & more violent. I would like to try Silhouette since I've read quite a few posts on this forum & people seem to really like it. And of course, the experimenter in me just wants an excuse to load & shoot! Seriously though, I want to just settle into the load that works for me. Fortunately, I am semi-retired (VA disability), so I have allot of time on my hands, & shooting & reloading are my passion. I appreciate all comments...
