[QUOTE="Hugnot, post: 2778392, member: 115658"] I have found 4000MR to have a similar burn rate as RL19. The burn rate list in the Hornady manual places 4000MR between RL19 & H4831. 4000MR is a good powder for many cartridges; I have used it in the .22-.250, .243, 6mm Rem, 6mm AI, 6.5-06, & 300WM. It has less density than other ball powders and provides a better case fill with less empty space. 4000MR velocities are often the highest listed for certain cartridges & bullets. Made by General Dynamics in USA. double base with NG. [/QUOTE]
