I have three .54s, they all prefer a .530 ball and .018 pocket drill patch. I tried #40 pocket drill cloth from Joann's a couple of years ago, it is really tough stuff, I will never go back to ticking after using it. All of my .54s shoot better with a stouter load, I use 80gr of 2F in my GM and Rice barreled guns and 85gr of 2F in my Hoyt rebored gun. I coned 2 out of the 3 with a Joe Woods coning tool for easier loading.
I have a lot of molds; I like the new CNC made Lee 2 cavity molds. A few years ago you could buy one for $19, they are now up to $38. Ebay has the best deal at $38 and free shipping, with TOW they cost a little less but you have to pay shipping.
I bought a TC Gray Hawk at a flea market for $90 a few years ago, it was unfired. I didn't need it so I sold it for $225 a month or so later on the M/L Forum.
