In my CVA/BPI Beartooth, I use the smallest ball (.490) and the thinnest patch I can find. I'm currently making my own patches fromsome linen material I have on hand. Anything else is just too tight to fit down the bore.
Another one of those, "It depends on your gun" things, I guess.
But lemoyne's recipe might be a good one 'cause it's tailorable to each gun!
