Meet a fellow at the range that is a collector of Evens fire arms. He had three with him, a rifle, carbine and an octagon barrel sporting rifle. He gets his ammo from a company in Colorado Spring and allowed me to shoot one of my choice. I tried the carbine and found it to work well. Hit 4” chicken plates at twenty five yards every time. These rifles hold a lot of cartridges in a rotating magazine in the butt. And the hammer spur is on the bottom of the lever. Weird design by todays thinking that worked well at that early day of repeating arms.
