Finally got around to a black powder casting bonanza (2 sizes round ball, two 45 conicals, a 54 conical and a 54 minie). The minie is a long discontinued Lyman hunting minie with relatively thick skirt walls and it is designed to take heavier charges. I haven't ever shot one before. I know I need to lube the grooves. Lube the base? I assume a wonder wad under the bullet is a bad idea? Only reason I ask is that this rifle shoots fer better with a wad under round balls and conicals.
