Not a bad-looking thumb, Boyd!
Probably still more point-blank shooters load at the range/match. I fought it for awhile, but once I decided to try it, I do all my load work-up right at the range. For our matches, I still preload because there are too many things that need to be done to have time to load. I have not reached the level where I need to "tune" my 30 BR during a match. It is a pretty flexible load and my abilities are more trouble than the load at this point.
It's amazing how comfortable it is to load at the bench or table with a Combo Press, a Harrell's measure and the necessary components. I had days this summer, as a partially retired old guy, I went to the range at 8 a.m. and stayed 'til 4 p.m., loading, shooting, cleaning all day. Talk about how to spend a day!
