[QUOTE="Buttermilk, post: 1416551, member: 5262"] In my XP-100 7mm RSAUM Bartlein 17.5" bbl, I tested briefly H1000 and IMR7977. Using H1000, I was able to go up 3-4 grains more in powder charge than IMR7977. In fact, if I recall correctly, my starting charge of IMR7977 was 63.0 which gave pressure right off with very very stiff bolt lift. I think I went up to 67.0 gr of H1000. I need to revisit the IMR7977 again, but found a good load using H1000 and the Hornady 162 ELD-X bullet, so I haven't went any further with testing. [/QUOTE]
