What size loads for my muzzle loader?

I went with the red dot scope last year and I like it. I'm still having a hard time grouping at 100 yards with the red dot. It's just too hard when the dot almost completely covers the target. However, I did shoot a buck last year at 130 yards. Went right through the vitals, lucky shot.
