I've also found it difficult to work up a good load in my Omega. Since I'm hunting CO, I have to use conicals. The best I've worked up so far is 460 No Excuses with 120 gr 777. I get about 3 in groups at 30 yards. I am not excited about that and have decided that 50 yds is my shot limit this year. The platinums sound interesting, but I don't think they are legal in CO. I think I can only use 100% lead. I have also tried MaxiBalls and Great Plains. Now, Shockwaves shoot great at 100yds.........
