BARRELS WE MAKE

Match Barrels


"Standard Match": Our Standard-Match barrels are supplied in both stainless and chrome-moly steel. These barrels are made using conventional rifling button designs and are available in many twist rates and land/groove configurations. Standard-Match barrels are carefully hand-lapped for excellent bore uniformity and surface finish. These barrels are capable of excellent accuracy potential and are recommended for most hunting and varmint shooting applications. Standard-Match barrels are available as blanks, contoured barrels, and prefit contoured barrels.

"Super-Match": The PAC-NOR Super-Match barrel is our premium grade rifle barrel. These barrels can be supplied in stainless or chrome-moly steel. Super-Match barrels are made using a proprietary rifling button design which yields barrels that have an extremely uniform rate of twist for the ultimate in accuracy potential. Super-Match barrels are designed with a unique land/groove geometry which ensures a good bullet gas seal with minimal bullet distortion. This special land/groove configuration also substantially reduces metal fouling in the barrel when the barrel is properly broken-in. All Super-Match barrels are carefully hand-lapped to a fine lustre finish and exhibit the exceptional dimensional uniformity required for the high level of accuracy possible using this product. Super-Match high performance barrels are recommended whenever the ultimate in accuracy is required. These barrels are supplied as blanks, contoured blanks, and prefit contoured barrels.

Selecting Barrel Twist Rates

Our caliber and twist rate chart (see below) indicates the twist rate recommended for use with normally manufactured ammunition. Today's handloader, however, has access to a wide range of heavier and longer bullets; a faster rate of twist may be required to stabilize these bullets. For example, a 12" twistbarrel will stabilize a heavier or longer bullet than will a 14" twistbarrel. Basically, the twist rate you choose should be sufficient to stabilize the longest and heaviest bullets you plan to use.

Special Barrel Configurations

PAC-NOR has the capability to make barrels with special requirements such as twist, rifling configuration, and bore and groove dimensions. We have made barrels for various ballistic labs, and arms and ammunition manufacturers. Since most of the tooling must be specially made, this type of work is done only on a written quote basis. Please supply us with drawings for your requirements by mail or fax so that we may accurately process your quote.
