So, I had an idea for a 12 ga. slug with a mould I had on hand. It is the Lyman 16 ga. foster slug (1 oz.), which fits well in a 12 ga. wad. The barrel I have in mind is a Pardner 12 ga. with a 3-1/2" chamber with a full choke. Mostly, it is a turkey barrel, but I would like to be able to take a deer with it. I tried to push a slug down the barrel in a wad, but it stuck at the choke with light hand pressure, but so did an empty wad. My major question is just how much pressure is it safe to require to push a slug out of a barrel. The slug did not fall free from the wad and choke at the sticking point, if that is relevant. I however did not push with great force to try to get it through.
