Last Fall Argo posted for me pictures of a WC Scott I bought at the time. It’s a great shooter but it’s a bit of an effort. The gun is circa 1874 and has no choke. The locks are rebounding, but with a half cock. An “11” is stamped on the barrel flats. Bores are .768, but an RST round will not go into the chambers. Hand loads I make for my Parker 10 won’t fit either. I cranked the resize collet on my Sizemaster until resized hulls would fit. Happy Day. Would anyone hazard a guess as to why Scott would make a 10 gauge with such tight chambers: a 10 bore with 11 bore chambers? Maybe made for brass hulls? Proofs are black powder.
