Good evening all ? This is my first post on this board and I hope you can give me a little advice or send me in the right direction. I have owned a 54 Cal Renegade(Double Triggers) for yrs and have never been able to group anything. My first shot I would be able to hit a basketball, 50yds, but after that ?.......LOL Know one knows ! I had my barrel checked, and it's ok. I have the gun scoped and everything is tight. So I tried cleaning after every shot, even letting it cool. Same results. Now this is with a round ball. So I'm told by others I should go to a sabot. Here's where I need your help ? I've heard a lot about "Powerbelt" Would this be a good choice ? So I guess what I need is a good round, the weight, proper size, and in general the amount of powder. Currently I use FFFg........ Sooooo ? Thats where I'm at ? Can anyone assist ?......
