Description

VERSATILITY

• The .243 Winchester itself is a highly adaptable caliber, known for its flat trajectory, moderate recoil, and effectiveness in both hunting and target applications.

• The 1:10 twist rate is optimized for lighter projectiles (typically 55-87 grains). Capable of stabilizing most all 6mm hunting style projectiles (up to 100 grains), making it suitable for varmint hunting, predators, and even some long-range target shooting.

• A 20″ barrel length maintains good velocity while being compact enough for easier handling in dense terrain or tree stands. Long enough to achieve full burn rate to maintain exceptional velocities that predator hunters desire. It also pairs well with silenced applications, keeping the length short enough to easily maneuver.

RELIABILITY

• Carbon fiber barrels are known for their rigidity and heat dissipation, reducing barrel whip and maintaining consistent accuracy even during extended shooting sessions.

• Highly resistant to environmental conditions, meaning they won’t corrode or degrade as quickly as traditional steel barrels.

LIGHTWEIGHT

• The lighter weight of carbon fiber construction significantly reduces overall firearm weight, making it a great choice for hunters or shooters who cover a lot of ground.

CUT RIFLED BARRELS BENEFITS

Cut rifling is one of the oldest and most precise methods of barrel manufacturing, known for producing highly accurate, durable, and consistent barrels. This process involves removing small amounts of material from the bore in multiple passes to create rifling grooves.

• Superior Accuracy – Cut rifling produces consistent groove dimensions and minimal stress on the barrel, leading to exceptional accuracy and shot-to-shot consistency.

• Increased Barrel Life – Unlike button-rifled barrels, which can induce stress into the metal, cut rifled barrels maintain structural integrity, resulting in longer service life.

• Better for Custom and Match-Grade Applications – Since each groove is individually cut, this method allows for precise control over twist rate, groove depth, and bore consistency, making it ideal for high-performance shooting.

• Stress-Free Manufacturing – Because the process doesn’t introduce additional stress into the barrel, there’s no need for post-manufacturing stress relief, reducing potential warping or accuracy degradation.

• Consistency with Various Bullet Types – Cut rifled barrels perform well across different bullet weights and profiles, making them highly versatile for different shooting disciplines.

TAKEAWAYS

• Ideal for predator & medium size game hunting applications (coyotes, hogs, whitetail deer).

• Supports varmint and predator control with high-speed, flat-shooting rounds.

• The carbon fiber construction enhances accuracy and durability, making it a great long-term investment.

Proof’s patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made in our firearms division. These blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin developed by their advanced composites division, PROOF Research ACD. The aerospace-grade carbon fiber Proof uses has a specific strength up to 30 times that of stainless steel and a specific stiffness up to 7 times greater than steel. But strength and stiffness are only part of the equation. Heat conductivity and thermal expansion are also of paramount importance when developing a match-grade carbon fiber barrel. Proof’s helical wrapping pattern favors the longitudinal thermal diffusivity of the carbon fibers (along the length of the barrel) allowing them to more efficiently dissipate heat emanating from the barrel rather than insulating it.

THE ONLY CARBON FIBER-WRAPPED BARREL APPROVED FOR USE BY THE U.S. MILITARY: Because Proof’s barrels are engineered for thermal performance, they also move heat very effectively through the wall (thickness) of the barrel, greatly increasing heat transport and resulting in barrels that cool faster and maintain accuracy over longer sessions of fire. The end result is an aerospace-grade, high-fiber content composite barrel that is stronger, lighter, as accurate as the finest precision steel barrel, and maintains its accuracy in the most demanding environments. They didn’t invent carbon fiber-wrapped barrels. They just perfected them. Up to 64% lighter than traditional steel barrels of similar contour Match-grade accuracy Improved heat dissipation for cooler and longer lasting barrels No point-of-impact shift during high-volume fire Reduced harmonic barrel vibration. Unprecedented durability.
