10 bore?
Nah, just a 20 gauge Colerain Turkey Choke barrel I picked up here. The whole gun is scaled down and will come in under 7 pounds I think.
Barrel: 39” 20 gauge Colerain octagon to round
Lock: The Rifle Shoppe Wilson lock castings set, arduously self-assembled
Buttplate: formed of 0.090” thick brass plate
Side plate, trigger, muzzle cap (in progress) self-made
Guard: Reeves Goehring HVF guard, bought back when they were $18
