I'd like to hear more about your IMR4831 loads.

I usually use H4831 with a 140gr in 6.5x55, 45.0 in the mausers, 47+/- in the modern rifles.

I try to use the temperature tolerant powders like most of the Hodgdon line, since in AZ I could load up a bunch one month in the 70F fall/winter/spring and shoot it for fun at the range a few months later in the summer when its 110F. (yeah we shoot in that kinda weather down here!)

My IMR loads mirror your H loads in weight. I don't hotrod the cartridge, but IMR 4831 is a slight bit faster burning no? 120 to 140 grain bullets are my mainstay, and I heavily rely on 129 Hornady Interlocks and 139 Scenars within that range. Lapua brass lasts seemingly forever with those loads in a Ruger #1A when primarily neck sized (partial full length sized actually).
