Green Mountain Muzzle Loading Pistol Barrels are machined from high quality American made bar stock, A.I.S.I. 1137 modified, stress relieved, annealed, certified rifle barrel quality steel. All barrels are drilled from solid stock, reamed to a high degree of smoothness, then optically checked for straightness. Very close tolerances are maintained. Diameters vary less than .0002"; within any bore.
Cut Rifling Specifications:
- Each pistol barrel has eight lands and grooves.
- Grooves cut .008 to .014"; deep, in .45 to .54 caliber.
- Twist is 1 turn in 20 inches for .45, .50, .54 caliber .
Green Mountain Muzzle Loading Pistol Barrels are set between centers, and milled octagonal, insuring a perfectly centered bore that will be concentric with the exterior.
Green Mountain Muzzle Loading Pistol Barrels are premium quality barrels in every sense! A small trade mark and caliber mark is stamped near the breech.
