Guys, is it better to do an OCW test at 100yds or 300yds? I have been using RL15 with good results, but is this powder heat sensitive? It looks like most of you like varget and I want to do an OCW using it. I normally run my test at 100yds, but to my thinking it should show me more if I do it at 300yds. Would like your opinions. I am using 175 SMK's and 178 Amax's
