I have had a Hern Coehorn for several years. It is steel lined 2.25" bore about 10" deep, has a flat base [no powder chamber]. The outside casting is rough, it would take a lot of grinding & polishing if you want a smooth finish. I have never found a good supply of cans for projectiles, 2 3/16" is a real nice fit. Most cans I find are 2 1/8", to loose. Anyone know of a good ammo source of 2 3/16"?
