A Rice .50 caliber Fast Twist barrel measures 1" across the flats octagon. Rice doesn't make the .50 caliber in 15/16" octagon. The .45 caliber is available in either 15/16" or 1" straight octagon. Barrels come standard at 28" & 32" long, with the underrib, 2 ramrod pipes, and the barrel wedge key underlug installed, in the white (not blued). The front sight dovetail is machined into place. I do not recall if Rice drills & taps the barrel for the traditional open rear sight. (edit: Williams sights are provided)
Groove depth is 0.0035"-0.004" deep.
The barrels come with a Rice percussion snail drum hooked breech that fits the Thompson/Center hooked tang. The drum takes a standard 1/4"-28 threaded nipple. Platinum-lined nipples are recommended due to the high breech pressures generated by heavy lead conicals in a fast twist barrel.
The .45 caliber is available standard with a 1:18" or 1:28" rate of twist. The .50 caliber is available standard with a 1:24" rate of twist. Other twists are available upon request.
As a note of interest, these Rice drop-in barrels are available in standard round ball calibers & twists in Rice's standard muzzleloading steel. Depth of the grooves is 0.010"-0.012" deep.
(15/16") .32, .36, .40, .45, & .50 caliber
(1") .32, .36, .40, .45, .50, & .54 caliber
.32, .36, & .40 caliber = 1:48" twist
.45, .50, & .54 caliber = 1:66" twist
Twist rates can be changed upon request.
