I posted this elsewhere, but I might get a better response here.
Here is a question for you folks- I need some kind of weird, obscure, or uncommon type of highly accurate single shot rifle that I can have my 50-year-old reformed hired killer use in my next book. I don't want just a plain old Sharp's chambered in .45-90, I would like it to be something rather unique, maybe in an unusual chambering, something that would've been used in 1870s and 1880s. Got any ideas?
