I have a 50 cal rossi muzzeloader. I shoot 300 grain hornady lock n load speed sabot. I use hodgdon triple seven pellets 150 grain. My muzzleloader use a 209 shot gun primmer. Is this to much powder or just right. I would like to start using my muzzleloader for shot gun season. I seem to get alot of shots at 150-200 yd range at standing deer. But don't take them because there out of range for my shotgun. Thats why I want to use my muzzleloader.
