[QUOTE="Hugnot, post: 2266802, member: 115658"] 4000MR has proven to be an excellent powder for me in .22-250 (68-75 gr. bullets), .243W & .300WM. Data for 243W. & .300WM in Hornady manual. Burn rate sort of like RL19. Made by General Dynamics in FL, ball powder, does not appear to be extremely temp sensitive as I avoid using it when temps are above 90*, just as clean burning as others. MagnetoSpeed chrono velocities for 3, 71.5 gr. 4000MR, 178 Hornady ELDM, 3144, 3158, 3149. Next 3 rounds did .5 group at 100. Next 5 rounds - 200yd zero, last 5 300yd zero. I hope to get 8 lbs. asap. Alliant says "it's good for heavy lifting" I shot a small rodent using it with a 87 Vmax in my .243W over 400 yards a few years ago (1 shot but I waited until it rested on ground). Hodgdon burn rate chart does not reflect true burn rate of 4000MR. [/QUOTE]
