I have had 4or 5 go out without any thing I knew of being wrong, I personally believe that the difference is in the type of powder. The main difference to me is between the type of detonation you get from black powder and smokeless powder, I personally do not believe that the cartridge has any thing to do with it I also believe that they work for a lot of people because of lighter loads and less shooting. It has taken 1200 or so shots to scramble them in my experience. There is a certain brand of scope I like on my center fires that I will never put on a muzzleloader again. I won't mention the brand as it seems some people think you are stepping on toes if you don't have good results with the brand they like. Lee
