Scrider1, no offense but do you not enjoy shooting your gun? Are you limiting your max range to 50 yards, or would you like to know what your bullet is doing at 100 or 125 yards? Your barrel isn' t even broken in yet. I for one like to tinker with different loads and bullets to see how they work in my gun. That' s part of the fun of muzzleloading for me. You CAN change up everything if you want. I like to try a different bullet every year at the range, and this year I' ve tried 2 different powders also. All I can say is to each his own.

Carcano, it sounds to me like you are getting a plastic fouling buildup in your barrel. I don' t shoot sabot, but that' s one of the drawbacks to using them. Some people I' ve shot with have to clean after every 1 or 2 shots to get their best groups with sabots. Make sure you have a good nylon bristled brush and some plastic solvent, and scrub the barrel good when cleaning. Then, take it back out and compare groups. I' ll bet they tighten back up after thorough cleaning. Good luck.
