The whole swap a slug into shot data didnt work very good for me and its pretty hard to find slug data so might as well share (I'm not your mom, you are responsible for yourself)
Fed top gun hulls
Fed 209a
39.5gr longshot 189 charge bar
1oz lyman.678 roung ball hard cast bhn 20+
Fed 12S0 wad or claybuster equivalent (fits reasonably tight in the barrel)
Lee load all star crimp
Seems reasonably accurate as far as I can tell with bead sights, they do bounce pretty good so make sure your backstop is steep....
I also have a green dot load that isnt as heavy
I will update this with velocities once I find my notes or chrono them again
