Don't go nuts, but loading a conical backwards with a light charge makes fantastic wadcutters and with an old Ruger Old Army, I was printing super tight groups and the holes looked like they were cut with a die. That was with the casting from a Lee .456" 220 gr. mould.
After all, the face of a RB is not that much different than that of a conical nose. The bearing surface will be the same either way. I've use this system also with a .44 Remington copy using sized and lubed Lyman 225 gr casting that I use in the .45ACP. Loaded backwards over 20 gr. of Pyrodex P gives great groups and like with the ROA, looks like a cutting die was at work on the paper. The Bullet is simply run through my old Lyman 450 sizer/luber at .451" and lubed with Lee Alox/Beeswax. Works great.
There's your wadcutters fellas,
Wade
