Looked at the parkerguns thread but did not download the short ten spreadsheet. I've been reloading my 1885 10 gauge Lefever C for the past several years. I use Hodgdon Longshot and either buffered Bismuth or NICE shot for Canadas and duck. Don't use a progressive press to make the 10 gauge loads/reloads. I rarely use 50 in a season. Start with primed 10 gauge 3-1/2 inch Federal shells. Cut them down to 2-7/8 with a tool (from BP, if I recall), put in the load of Longshot appropriate to the weight of shot, overpowder card wad one or two fiber wads, and then an SP-10 shot cup, a 16 gauge cushion wad or not in it, depending on quantity of shot, last an overshot .125 card and roll crimp with an antique British tool. Have loaded up to 1-3/8 oz of shot for geese, but usually use 1-1/4. Have reloaded spent hulls using old British tools to reprime.
Have not tried brass shells.
