Proof Research Steel Bolt PXT 224 Cal
PROOF Research PXT carbon fiber and steel barrel blanks combine next-generation rifling technology with the performance and accuracy that have defined PROOF barrels for years. PXT - PROOF Exponential Twist - is a complete rethinking of conventional rifling geometry and twist progression, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the rifling.
By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore, PXT technology helps reduce wear, improve consistency, and create less felt torque during firing for improved recoil control and the ability to stay on target more effectively.
In controlled testing, PXT barrels have demonstrated 30-100% increase in barrel life while maintaining the accuracy standards expected from a PROOF barrel.
Designed for custom rifle builders and gunsmiths, these blanks offer a premium foundation for lightweight hunting rifles, precision long-range systems, and modern high-performance rifle builds where consistency and durability matter most.
