I don't see a category that would cover doubles, except for this one. May I proceed?
I've got a Russian/Remington, in 45-70 Govt. I love it ,in spite of not finding it easy to regulate the bbls.
I bought it to use for a Moose hunt several years ago. Never saw a legal moose but had fun anyway.
Poor health in the ensuing years has prevented me from exploring it's possibilities. Oh well--it's something that I can look forward to, until----.
