These are a pair of Remington 45-70 rolling block rifles dating from the 1870s.
Lots of fun and great folks involved with cowboy shooting. It’s a growing segment in sport shooting – 100,000 strong at this point.
UPDATE: I’ve watched a bazillion Clint Eastwood cowboy movies, and while I enjoyed them all, in the back of my mind I was thinking, “Come on. In the real world, nobody can shoot like that.”
I just watched a bunch of people shooting the same kinds of guns, and the best of them were, indeed, shooting just like Clint.
