I normally shoot the Saeco 1881 bullet with my bp load with great results. I have been casting the Lee 405gr HB, tumble lubing
them with liquid alox, and loading them over 35grs of 3031. I get one inch groups at 70yds. I don't use any fillers or wads, just the powder and bullet. I want to use the same bullet with Goex 2F and lube them with my Lyman sizer with SPG. I will compress the load and use a newspaper wad over the primer pocket. Will using two .030 fiber wads between the powder and the base of the bullet cause the hollow base not to expand? I am hoping to get the same or better accuracy using black powder. I casted a few hundred of these Lee bullets and will be using them in my Sharps and Trapdoor original.
