The subsonic Pig Gun project has begun!
Mock-up.
The bore turns out to actually have 'square' rifling under the rust! I had to straighten the barrel before cutting it as the bend was right where the cut was to be. After fire-lapping it looks like I got it straight. More fire-lapping is needed but already a patched boolit shoots without cutting into the lead core.
The cartridge and some boolits.
The boolits in the pic are a 230gr hollow nose and a loaded 245gr flat nose from the same mold. That boolit is going to hurt a pig or any other critter real bad!
The scope mounts and suppressor are still to be built.
