[QUOTE="vancewalker007, post: 1648956, member: 66917"] Another new powder that is very temp stable and will fill the case nicely is IMR 8133. And as suggested, H1000 should settle your ES down. I've easily pushed my ES down in the low teens in my 6.5 PRC using H1000 and very careful reloading. Even if you can get down in the 20s you'll have something. You don't noticed major elevation issues at 1000 yards until you get over around 20-25. Make sure your case dimensioning is consistent, ie. consistent base to shoulder length, base to case mouth length, neck tension (via correct bushings). Make sure your charges are at least on the same 1/10 grain. Also you need to be sure you're not loading on a velocity jump point and that you're loading in a flat velocity node. [/QUOTE]
