[QUOTE="Buttermilk, post: 1732044, member: 5262"] In my XP-100 7mm RSAUM, I've had really good results using H1000, H4831sc, and IMR4451. Barrel is a Bartlein 5R, 17.5" long, with a FB of 0.140", 1:9" twist. Nosler 150 gr ABLR was used with the IMR4451. I hit pressure at 58.0 grains. Accuracy initially was stellar at 0.25 MOA, but wasn't repeatable. Velocity was 2850 fps. I used H4831cs with the Berger 168 VLDH with exceptional accuracy as well. 60.0 grains is the max I've loaded to. Gives sub 1/2 MOA (best has been 0.24 MOA) at 2700 fps. H1000 has given me the best combination of accuracy and speed with the Berger 168 VLDH. I've went up to 67.0 grains, but have slightly better accuracy at 65.0 grains. I've still got some more load development to do with H1000, but so far, it's been 1/2 MOA or slightly better. I've also used 65.0 gr H1000 with the Hornady 162 ELDX with 1/2 MOA as well. It's been a consistant 1/2 MOA load so far. I also play some with IMR7977 since it is supposed to be similar burn speed to H1000. In my gun, I hit pressure at 63.0 grains of powder, which is where I started at. I stopped working with it after the 63.0 grain charge. I had better results with H1000. Hard to go wrong with H1000 and H4831cs in the 7 SAUM. In my 7mm RSAUM, I've pretty much settled on H1000 for the bullets I plan to shoot. [/QUOTE]
