[QUOTE="Michael Eichele, post: 627734, member: 1007"] I have been doing some load development with the 140 AMAX in the 6.5x284 with H4831SC, H4350, H1000, RETUMBO, and RL17 in a 27" barrel. So far (all things considered) H4350 has done the best. I have the lowest ES/SD with H4350 and 210M primers. I shot a group tonight right at 1-1/4" at 300 yards with 46.5 grains. 2891 FPS. I am going to proceed up to 48.0 grains. I don't see much point in going past 48. I am nearing peak velocity with H4350 at 46.5 Another good load was 50.5 of H4831SC which shot 1-5/8" at 300 yards. ES was a bit much with all the charges tested. 2840 FPS at 50.5 grains. I can easily work up to 52-53 grains. RETUMBO has shown promise in accuracy and definately velocity. 59.0 shot just over 3100 without any pressure signs. 59.0 while not 'hot' is about all I can fit in the case and still seat bullets. RL17 has also shown great accuracy potential with over 3100 FPS as well. I think 3100 FPS came around 50 or 51 grains. I am sure they will go faster but I am not willing to test this out on my rifle's freshly cut throat. The verdict is still out with H1000. Hope that helps! M [/QUOTE]
