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.........
You can use ANY .50 caliber powerbelt bullet in Colorado. ALL .50 cals are legal. So if you shoot PB's better in your Omega, by all means, use them.
