I built the exact same kit last year. Shoots great. I settled on 0.015 lubed patches and .530 balls. I use Goex 2F, anywhere between 50 and 100 grains. Be prepared to do a fair amount of filing on the front sight to get dialed in, that sucker is tall to start with. I do not swab between shots. I clean up with hot water and a drop of soap, rinse, dry, re-coat everything with bore butter. An old .30 cal brush with a patch on it is just right to get the breech clean and dry.
