[QUOTE="JeffVN, post: 1166912, member: 2261"] I have run my 28" tube 7WSM (long throated to over 3.200" COAL w/ Berger 180 Hybrid) consistently at 2,900+ fps. No pressure and the brass lasts for well over 10 reloads. I've run at the 2,900+ node with RL-25, H4831sc, and H1000. I have no doubt you can find what you need with H1000 or the other powders that you are testing. RL-26, IMR 7977 and IMR7828ssc didn't exist back when i developed my 7WSM loads (but my 30-06AI loves 7828ssc under a Berger 185 Juggernaught), so its potentially worth a look for me as well. velocity consistency is only one factor in finding your load, but it all comes down to how it shoots at distance. I don't declare it done until it shoots well at 400 meters+. if it does, then it has in virtually all circumstances shot well at 1,000 yards and at 1,900 in the desert. As someone mentioned earlier, I've had loads that didn't hold super tight ES or SD but they shot bug holes and others that looked great on paper that barely held a minute. Jeffvn [/QUOTE]
