Just came in off the truck. Zero markings other than

M2
1977
1:22
45 70

The barrel width is 1 1/8" - Length 30"

This is an underhammer but more of an inline set up with a scope and modern style walnut stock. Super heavy duty like for competition shooting.

Any ideas what I got?

.45-70? That's a centerfire cartridge.

You got something good, if a bit heavy.

M2 is probably the serial number, 1977 date made, 1:22 ? twist ?, 45 70 barrel was a surplus barrel that Dixie Gun Works sold 1000's of, of which many showed up as bench guns at Friendship in the 70's and 80's. From the shape of it, from the shape of the rifle it looks like some of the under hammers that Ron Long built and wrote about.

Jon, several of the muzzle loading builders in Denver built these rifles, some with interchangeable barrel systems for smaller and larger calibers than what you now own.

I had one that the barrel had been turned down to a 1 inch tapered barrel rebored to .500 caliber slug gun style like yours. Heavy slugs up to 600 grains, half-stock - .500 caliber 1-24  fast twist,  shallow .040 groove barrel that would shoot elongated lubricated slip-fit bullets, equivalent to the later 50-140 black powder cartridge. We shot BlackHorn 209 with 5 grain black powder to make this baby go.

welp, I got a ton of .440 round balls so I loaded up the rifle with 50gr 3fg GO, .020" patch and .440" round ball. I plan on taking a few shots tomorrow and see how fun she is. With a 1:22 twist, I thought it best to keep the charges light. I may end up keeping her and refinishing the stock to my liking if she shows promise!

No stock or barrel work on this one! With the design, its made for a firearm.

Man what a hoot! I shot it at 25 yards to zero the scope and she shoots awesome! A nice loud boom and zero recoil. Accuracy looks outstanding so far, but i am only shooting 25 yrds. I am going to swab the bore, reload my powder tubes and back it out to 50 yards and use my sand bags. It doesnt have an expensive scope, but i am really surprised by the clarity of the glass, very bright and clear.
