H-S Precision is the world's leading supplier of pressure, velocity and accuracy test barrels. Ammunition companies such as Olin, Remington, Federal, Hornady, PMC, Black Hills and powder companies such as Primex (Winchester powers), Hodgdon, IMR and Accurate Powders all specify H-S Precision ballistic test barrels for their critical quality control requirements. We also supply test barrels to numerous domestic and foreign government agencies.

H-S Precision's ballistic test barrels are manufactured with the same exacting precision as our Pro-Series match grade barrels, though they must all conform dimensionally to SAAMI, CIP or military drawings. We use only 416 or 416R stainless steel that is heat-treated and stress-relieved to our specifications. H-S Precision produces ballistic test barrels in all calibers ranging from 17 Rem to 50 BMG. Shotshell and rifled shotgun barrels are also available. H-S Precision's production of all necessary tooling, such as reamers and rifling heads, coupled with the cut rifling process, facilitates the production of virtually any experimental or prototypical barrel in a timely manner. H-S Precision also installs any type of pressure port and can supply piezo plugs and pressure pistons.
