Model 12 "22 Long Rifle" only ???

[John Gyde]

Rem M/12s were stamped LONG RIFLE ONLY in 1909 and up to mid-1910. The change was done before serial #51,277, although Rem had a habit of phasing in the changes so it's possible that not all late-1910 rifles had the caliber change. There should be several other features on your rifle that are different from later production. There are twenty-three pages on the M/12 in our book so all changes can't be listed here..

Yours is mid-1910. I would not shoot shotshells in it. Did you mean Shorts? If so, I might try low velocity shorts but not many and not the new hi-vel stuff.
