Manufactures barrels that are Match grade quality with bench rest capability. Rice barrels do not require lead lapping or extensive shooting to break in.
CNC RIFLING MACHINE: Our proprietary infinitely variable CNC rifling machine uses a traditional Springfield type rifling head to single hook CUT each groove.
CALIBERS: 32, 40, 45, 50, 54, 58, 62 rifled or smoothbore.
GROOVES: Round bottom CUT rifling .016 deep. Standard in swamp barrels. Square bottom CUT rifling to .012 deep (special order in swamp barrels, and delivery time may be extended).
NUMBER OF GROOVES: 32 and 40 - 6 groove 45 to 58 - 7 groove 62 - 8 groove
TWIST RATE: 32 and 40 - 1/48 45 to 54 - 1/66 58 and 62 - 1/72
NOTE: Other twist optional at additional charge. Delivery time may be extended.
CROWNING: 60 degree lathe cut and polished. PLUGS: Swamp barrels fitted with flared tang flint plugs, which are manufactured by Quality Machine and Tool. All plugs fitted to a depth of .550, and each plug is absolutely square bottomed and timed.
STRESS RELIEVING: Each barrel blank is heat treated in an electric furnace. This procedure eliminates stress and warpage and helps control harmonic vibrations and/or barrel whip.
PROFILING: Barrels are machined between centers on a planer mill following a template. We do not bow or arch the barrel in order to machine the profile. This eliminates subsequent straightening.
DOVETAILS: Barrels supplied for the Chambers kits will be dovetailed to his specifications.

BORE DIMENSION QUALITY CONTROL
After the rifling has been CUT, a carbide bore-sizing die is pulled through the barrel to insure bore dimension continuity and to eliminate 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.
CONING
"I do not offer coned muzzles and do not have personal experience shooting barrels so modified. Therefore, I remain neutral as to the practical merits of coning. My policy is to warrant workmanship and materials. Custom alteration such as coning voids the warranty.
"Recommendation: Should you elect to cone, shoot the barrel with its polished 60 degree crown for an accuracy base line. After coning, again obtain a base line for comparison."
Coning tools are available from Joe Wood, Amarillo, Texas 806-352-3032
CAUTION
DO NOT:
Cut dovetails or drill for barrel pin loops in the "waist" or smallest part of the barrel. Dovetails should not exceed .050 in depth.
DO NOT:
Short start the patched ball. Insure the patched ball is seated on the powder charge each and every time you load.
DO NOT:
Load with more than ONE round ball at a time and never attempt to shoot a conical bullet in a round ball (slow twist) barrel.
DO NOT:
Use excessive vice jaw pressure when clamping the barrel in a bench vice. The bore can be deformed (destroyed), and when loading the ball there will be a noticeable tight spot. To remove the breech plug, clamp the barrel 1" from the breech so as to not crush the breech threads into the plug threads. Swamp barrels require a shim to compensate for its taper, eliminating a single point of excessive pressure.
