My first 45-70 is far from old but is built on an original RB action dating to 1879 or thereabouts. Found a Spencer Machine Works SxS, Damascus barreled 12 ga w/hammers about 30 years ago. IIRC, patent date is 1873. AAs, 1 oz #6s and a light BP load (25 gr 1F) and felt wads - it is a hoot to shoot. Not fun if you light up both barrels at the same time, though.

BTW, I had a gunsmith go through the SxS to get his blessing before shooting it.

Someday I hope to be the person my dogs think I am . . .
