[QUOTE="J E Custom, post: 1534722, member: 2736"] I have not tried the IMR 8133 powder in mine so I cant help you with it, but the 300 rum is a great cartridge and is not finicky with powders as long as the right bullet is chosen for the barrel. Guys on this site are very good about sharing information to help but don't start with loads we share as OUR best loads because they may be to hot for your rifle so start lower and work up. Looks like 92.5 grains of IMR 8133 is max for a 200 grain bullet and 90.0 grains for a 220 grain bullet. Looks like Retumbo will edge 8133 out in velocity but the 8133 may be more accurate.
