[QUOTE="Rymart, post: 1294767, member: 3688"] H1000 is my go to powder for 338 LM. Never had an issue finding an accurate load with it. Seems like current reloading manuals and online guidelines are pretty conservative on charge weights. I'd start somewhere around 85 grains and work up watching for pressure. In my rifle, 91.5 gr was the ticket with 300 gr SMK's and the 300 gr Berger Hybrids. 92.0 + grains actually shot better, but pressure was too much. Seems like with the 300 class bullets and H1000 the high node is right at/over max pressure. This is with Lapua brand brass, Fed 215 primers, ~ 0.025" jump. Still testing the 285 gr ELD-M's with H1000, but so far with Lapua brass my node looks to be at 92.7 gr, pushing 2880 fps in a 27" barrel. With RWS brass, it's 91.4 gr at 2860 fps. This is with a Bartlein 5R barrel. Not sure if a factory barrel will get these velocities. [/QUOTE]
