Specifications and historical context

Period performance

This Model 1866 conversion earned its reputation after proving effective during the Wagon Box and Hayfield fight in 1867. That combat history enhances provenance and gives the rifle narrative value beyond aesthetics.

Condition notes

Key features to note: bright-finished barrel with surface staining, black breech, lock plate dated 1864 with 98% original case coloring, and a stock with only minor handling/storage wear. These specifics matter when evaluating authenticity and long‑term value.

Shooting, preservation, and the .50-70 cartridge

The .50-70 Government cartridge is a historically accurate chambering for this conversion. It delivers a heavy, low‑velocity projectile suited to the era’s tactics—effective for museum shoots, living history demonstrations, and controlled range excursions where original‑pattern ammunition or modern reproductions are used. Owners should prioritize proper black-powder safe loading practices and consult a qualified gunsmith before firing any antique firearm.
