I seem to get consistent results with the WSM's than I do with the Win mags and etc. After some work, I usually can get most guns shooting acceptable, but notice, things were very consistent with the WSM. I mean, my groups would show a gassian shape over the powder load. Starting load 3" groups, and it would go down and down and then groups start opening the higher I go. So it was easy to make a choice on powder load.
