You really need to find a mentor, as was previously suggested. You will find that if you ask 10 black powder shooters as to what to use, you will get 10 different answers, some good... some
not-so-good!!!
Eventually, you will find what supplies, cleaning items, tools, etc. you need that work for you... and a local mentor can be of serious help in such matters.
I wish there was one simple formula... one set of instructions... for this kind of thing, but there isn't. Go... find a MENTOR... and judge the mentor by how well his shots group together. If he is an excellent shooter, then listen to him... 'cause he's got it all figured out!!!
BTW, I also shoot a Traditions... a "Shenandoah" .50 caliber rifle... and Traditions recommends a .490 round ball with a .015" patch. I found that my rifle "likes" a .016-.017" denim patch with a .490 round ball. Don't forget to WASH your patch material BEFORE using it to take the "sizing" chemicals out of the cloth that the manufacturer put into it. I cut my material into 2-inch wide "strips" after I cut a 31" square of it.
I add the 1 inch (30-inches + 1-inch) because about a half inch of the cloth frays all around the parameter of the cloth when it's washed. Thus, I end up getting 15 strips of cloth 2-inches wide each (totaling 30-inchs). I place the ball on the lubricated strip (I won't tell you what I use to lube the cloth... you wouldn't believe it), and "cut" it at the muzzle with a very sharp knife after I use my short starter to push the ball slightly below the barrel's muzzle.
This yields a "perfect patch" around the ball without too much excess cloth ahead of the patch. I learned these methods from my MENTOR who was, at one time, the State Champion... and, at 83, he still wins a good many of the local black powder matches. I promised him I would not tell what kind of "lube" he uses... and this is why I can't tell you, but I use the same "lube" he uses... and it works really well.
Strength & Honor...
