Ron Smith of RKS Enterprises can do straight or gain twist barrels with any twist you desire in chrome moly or stainless steel. You can request either a 6 groove or 8 groove barrel or even fewer grooves if you desire. I have used the 8 groove barrel since the bullet aligns better and is more concentric in my opinion. His barrels are cut point precision cut where he makes 40 cuts for every groove. The barrels have a continuous taper of .0004" between the chamber and muzzle. The choke provides the best accuracy for shooting cast bullets (reduces ability of gas cutting around side of bullet). The gain twist reduces barrel wear by 10% to 15% for high pressure high performance use of his barrels. Ron Smith P.O. Box 635 Wimborne, Alberta T0M 2G0 403-631-2405 Again I post the accuracy from my 5 shot cast bullet groups shot @ 100 yards with a .32 RKS 8 groove gain twist stainless steel barrel ending in a 11.5 twist. I have made one or more rifles with RKS barrels in the following calibers: .22 LR, .218 Bee, .22-250, .223, .25 RKS, 6mm Remington, 6.5x55 Swede, .270, .280, .308, .30-06, .300 Win. Mag., .32RKS, .32-40, .35 Whelan, .38-55, .40-65, .45-70, .50-70. They have all had EXCELLENT performance in Schuetzen smokeless powder cast bullet rifles, Black Powder rifles and hunting rifles. Ron always says to select the weight and length of bullet you intend to shoot; in order to provide the best twist for gyroscopic stabilization before you order the barrel. Also he can consider how best to throat the chamber. Works better being able to start with the correct bullet instead of trying to test numerous bullets to work out your new barrel.
