Buttstock, I had a buddy in upstate NY who many years ago sent an 870 smooth bore barrel to PA and had it rifled. He cast his own round balls and loaded them in to a shortened, scissors cut wad. I don’t remember anything else but it was an accurate “rifle” and the round balls killed very well. Best regards, F01
I would love to have my 12 gauge Rem 870 rifled with a 1-100" twist for round balls. Do you remember who did the rifling?
