Thanks for responding to my question.
I'm not shooting for competition, it's just for personal enjoyment at this point. But I will keep your point in mind when I start shooting past 800 yards.
I did use Varget and IMR 4064 with pretty good results, however, I'm pretty much stuck with ball powder because I use a progressive press and the stick powder does not measure well (+/- .4 grains) with my powder measure. The ball powder measures +/- .1 grain at worst, with most drop being right on.
I have since discovered that Win 748 is slower burning then 760, but again it begs the question: when is a fast burning powder more desirable then a slow burning powder and vice-a-versa?
Experience is a very bad teacher because it first gives you the test and then teaches you the lesson.
