Just a FYI for guys loading short mags and some Ultra mags. MagPro has been becoming a popular powder in these (270 WSM, 7m Short, 300 ultra……) I’ve been shooting as much as possible this summer and am very pleasantly surprised with it. Very stable load and I’m not seeing any variance from below zero temps to shooting at 98 degree. Very pleased!
