By designing a bolt action barrel blank, Proof has opened up countless options for chambering in your favorite caliber and having the ability to fit a large variety of actions. These bolt-action barrels are available in a variety of calibers, lengths, contours and twist rates. Your bolt-action barrel will arrive ready for thread and chamber by your gunsmith.
*Wildcat Disclaimer
PROOF Research’s barrel blanks may be finished with a wide variety of custom chambers for standardized or wildcat cartridges per the gunsmith’s and end user’s preferences. As such, there is no guarantee of performance in terms of accuracy, muzzle velocity or bullet stability.
This is especially true for wildcat cartridges that have no standardized chamber, cartridge design or pressure limits. PROOF Research’s barrels have been designed for safe operation with the vast majority of known cartridges and within SAAMI and CIP pressure limits. If you have any questions about the safety or performance potential of your planned rifle build, please contact our Customer Service department.
