Match quality, no break-in period, no hand lapping is required. This barrel will shoot accurately from the very first shot.

Rice Muzzle Loading Rifle Barrels are set between centers and milled octagonal, insuring a centered bore, concentric with the exterior, with no "run-out". Each barrel is stress relieved in an atmosphere controlled electric furnace, to eliminate work hardening or barrel warp, and to dampen harmonic vibrations or barrel whip.

After the rifling has been cut, each bore is "ball burnished". A carbide bore-sizing die is pulled through the barrel, to insure bore dimension uniformity, eliminating any tight or loose spots inside the barrel. This critical procedure leaves the top of the lands smooth and polished, equaling the traditional lead lapping procedure. Rice barrels are Match grade quality, with bench rest capability.
