Which is recommended/which shoots better?
You are going to have to put in some range-time to determine this for yourself. We all do this for our own piece of mind and confidence. I will however, mention how I came up with my shot-strings. I like your choice of the Musket cap. If and when I use pellets and that isn't often, I shart out with one 50/50 then step up to one 50/50 and one 50/30. Then two of 50/50. I never go up to a three 50/50's.
Most of the time I shoot loose powder and my target load is 70 and my hunting load is around 90 to 95.
Be Safe !!!
