When evaluating a defensive firearm that doubles as a piece of usable history, we look for serviceable ergonomics, reliable mechanics, and craftsmanship that tells a story. This Winchester percussion side-by-side lives at that intersection — a museum-quality feel with practical characteristics that experienced operators can appreciate in training and display alike.
WINCHESTER CALIFORNIA PERCUSSION DOUBLE 10GA — a percussion side-by-side shotgun marked with Rudolphe Brauns Patent and dated April 17, 1866, featuring 30.5″ barrels to the breech plug and a rib inlaid with the gold inscription “Fine Damascus Steel”. 
Design & Craftsmanship
The side locks on this piece are of an unusual and historically significant design, both stamped Rudolphe Brauns Patent April 17, 1866. Barrels measure 30.5″ to the breech plug, and the Damascus pattern on the barrels is exceptionally clear and well executed. The rib carries a gold inlay that reads “Fine Damascus Steel,” a hallmark collectors and tacticians respect for both aesthetics and material quality. This is a California-built gun tied to Augustus and Rudolph Braun in San Francisco as noted by Frank Sellers.
Tactical Considerations for a 10GA Percussion Shotgun
The 10 gauge designation in the product name indicates formidable close-range stopping power. While the percussion ignition system requires different loading and handling compared with modern breech-loaders, training with this platform teaches fundamentals — muzzle discipline, loading procedures, and serious respect for powder charges. For collectors who also intend light display-range work or reenactment demonstrations, the 10GA delivers authentic recoil and presence.
