Introduced in 1989, the White Mountain Carbine was engineered for hunters who wanted a maneuverable black-powder rifle without sacrificing power. The 22-inch octagon-to-round barrel keeps overall length down while still delivering .50-caliber performance.
This example features the early fast 1-in-20" rifling twist, optimized for shooting shorter conical projectiles and modern sabots with impressive accuracy. The underrib provides a solid base for a ramrod and streamlines the barrel profile.
The American walnut stock sports a schnabel fore-end, gloss oil/varnish finish, and factory-installed sling swivel studs, combining classic looks with practical field features. A rubber recoil pad adds shooting comfort without detracting from the traditional lines.
The case-colored lock-plate carries factory scroll engraving, adding a touch of craftsmanship rarely found on production muzzleloaders of the era. The single non-set trigger and side-hammer flintlock action deliver crisp ignition and straightforward operation.
Made in the USA before Thompson/Center’s acquisition by Smith & Wesson, this carbine holds particular interest for collectors seeking pre-merger examples that represent the brand’s independent craftsmanship.
