Bill- I use CCI primers , Liquid Alox, and the info given with the Lee 38/55 Factory Crimp Die for the powder. I use the mininium charge. This is at a range of 50 yds. I tried 100 today but wasn't very successful. It was very hot and humid, so that could be a factor. Gonna try again when things cool off abit. I noticed all my Handi rifles shoot their worst during a heat wave.
