For me, my scoped CVA Magbolt has settled down into a very consistent shooter with at least a half dozen loads. The best group I've shot with it is just over .5" at 100 yards with 348 Power Belt's. The gun shoots under 1.5" with many loads. My White Ultra Mag is looking good too but I have not tried it with a scope and I'm still working on loads for it. So far I've found at least a couple of loads that shoot around 1.5" at 50 yards using the stock sights. I have a rear peep on the way so it should tighten up once I get that on it.

For traditional, my 50 cal Lyman GPH is hands down the most accuratemuzzleloader I have. With 460gr No Excuses and 70 grains of Pyro P I shot the tightest group I have ever shot (other than with my 7mm with an 18 power scope). The 75 yard 3 shot group measured .280" and was shot usingthe Lyman 57/17A sight setup that I have on the gun. That was one of the first loads I tried in the gun and was shocked at my good fortune. The same gun with my 54 cal GPR barrel does well also with round balls but not quite as good as the GPH.
