I'm looking at an old vintage single shot rifle with a barrel made by RCBS. I didn't know RCBS made rifle barrels in the past. Does anyone know when they stopped making rifle barrels?
OH Boy, that would be a piece of history. RCBS was founded by a man named Fred Huntington in 1943. My guess is that was one of his personal rifles made in the 40s or 50s.
If it was marked RCBS like the dies I would say it was associated with the reloading company some way but that looks like someone else had a company for barrels or gunsmithing with similar markings. R.C.B.S.C.O might stand for Rusty's Cobalt Blue Steel Company..... R.C.B.S.C.O.
This is one gun mystery I would love someone to explain but sadly all of the people who could likely tell us what you have are dead! Back in the 90s there were still a lot of the WWII and Korea generation left but now they are rather rare. Even the Vietnam vets are dwindling in numbers as they reach their 70s and 80s.
I have a Rem. rifle that is chambered in .243 RCBS. It is actually a Hart barrel and the chamber work was done by the RCBS gunsmith shop and not the reloading supply company.
