What is the proper load for my .54 Renegade to shoot roundballs accurately?
Lotsa variables involved, but I'd suggest that you make sure you are using a good
tough patch material that loads kinda tight. Then, set up a bunch of targets and shoot three or four shots at each. Start the first targ at about 50 gr of powder and go up 10 grains on each target. Wipe after every shot!! You will be able to see when accuracy improves or goes south. Study your patch material after each target (pick em up so you know after each target that they are the fresh ones). If your patching starts to blow out, you are over max
for that powder/patch combo. The search for roundball accuracy is to a large extent a search for good quality patch material. I always see answeres to questions like yours including a certain thickness of patch, eg. .015, .018, etc. My advice is don't bother to measure it. If it loads tight, but you are indeed able to load it, then try it. If it blows out it's probably due to quality of material, not thickness.
I bought two swatches of identical lokking pillow tick at wal mart last summer. One swatch red the other blue. One blows out one doesn't. they both feel the same when loaded. Once you find a really great patch material, go buy all of it

. Many shooters fret over lube, but I'll suggest that once you find a good patch material, it will shoot good with almost any lube :shock:
