The PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5 Made a Bold First Impression
The PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5 represents a significant investment for any serious rifle builder or precision shooter. Manufactured by PROOF Research, this barrel promises top-tier accuracy and performance thanks to its carbon fiber construction and meticulous attention to detail. As someone who’s spent over a decade building custom rifles and chasing the perfect shot, I was eager to see if this barrel lived up to the hype.
I’d been wrestling with inconsistent groups from a .264 Winchester Magnum build, a caliber I love for its flat trajectory and downrange energy. My existing barrel, while decent, simply wasn’t delivering the sub-MOA performance I knew the cartridge was capable of. I wanted a barrel that would not only improve accuracy but also reduce weight for long-range hunting scenarios where every ounce counts.
The barrel arrived securely packaged, and my first impression was overwhelmingly positive. The carbon fiber weave was flawlessly applied, and the stainless steel shank gleamed with precision machining. Picking it up, the weight savings compared to a traditional steel barrel of similar contour were immediately apparent, promising a more comfortable carry in the field.
I considered barrels from Bartlein and Krieger, renowned names in the precision barrel world. Ultimately, the carbon fiber construction of the PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5 won me over, promising both weight reduction and enhanced cooling properties. I was excited to finally start my build, anticipating tighter groups and more successful hunts.
Real-World Testing: Putting PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5 to the Test
First Use Experience
I installed the PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5 on my Remington 700 action and headed to my local range, a mix of covered benches and open-air space extending out to 600 yards. The initial break-in process was straightforward, following PROOF Research’s recommended cleaning intervals. Even during the break-in, the barrel showed promise, with groups steadily tightening as I put more rounds downrange.
The weather was typical for late spring: sunny with a slight crosswind that tested my wind-reading skills. I tested a variety of factory loads, ranging from 130-grain to 143-grain ELD-X bullets, carefully recording group sizes and velocities. The barrel handled the different loads exceptionally well, with no noticeable point-of-impact shifts between bullet weights.
The ease of use was immediately apparent. The barrel chambered rounds smoothly, and the recoil felt noticeably milder compared to my previous steel barrel, likely due to the vibration-dampening properties of the carbon fiber. I was pleasantly surprised by how quickly the barrel cooled between strings of fire, a significant advantage during extended shooting sessions.
Extended Use & Reliability
After several months of consistent use, the PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5 has proven to be exceptionally reliable. I’ve put approximately 500 rounds through it, and the accuracy remains consistently sub-MOA with my preferred load. The finish has held up remarkably well, showing no signs of wear or corrosion despite exposure to various weather conditions.
Maintenance is simple. I clean the bore after each range session using a copper solvent and bore brush, and I’ve noticed minimal copper fouling compared to my older barrels. The carbon fiber exterior requires only occasional wiping down with a damp cloth to remove dirt and grime. It definitely outperforms my previous experiences, making maintenance a breeze.
Compared to my previous experiences with other premium barrels, the PROOF stands out for its combination of accuracy, weight savings, and ease of maintenance. The consistent performance across a variety of loads and conditions has solidified my confidence in this barrel. It’s been a game-changer for both range sessions and hunting trips.
Breaking Down the Features of PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5
Specifications
- Caliber: .264 (6.5mm), a versatile caliber known for its flat trajectory and excellent ballistic coefficient. This allows for extended range capabilities and reduced wind drift.
- Barrel Length: 22 inches, a good compromise between velocity and maneuverability. This length allows for efficient powder burn while keeping the rifle manageable in tight hunting situations.
- Twist Rate: 1:7.5, optimized for stabilizing heavier, longer-for-caliber bullets. This is perfect for high BC projectiles like the 140gr+ class bullets that excel at long range.
- Barrel Breech: 2.5 inches, the length of the shank which provides a secure and stable mounting point to the receiver. This ensures a rigid connection for consistent accuracy.
- Shank Diameter: 1.20 inches, a robust diameter contributing to the barrel’s overall stiffness. This reduces barrel whip and enhances accuracy.
- Contour: Sendero, a profile that strikes a balance between weight and rigidity, suitable for both hunting and target shooting. The Sendero contour is substantial enough to maintain accuracy during rapid fire but not so heavy as to make the rifle unwieldy.
- Weight: 3 lbs-0oz, significantly lighter than a comparable steel barrel. This weight reduction enhances portability, especially during long hunts or competitions.
Performance & Functionality
The PROOF BBL CF BLANK BOLT .264 SENDERO 22 1-7.5 excels in accuracy and consistency. I’ve consistently achieved sub-MOA groups with handloads and select factory ammunition. Its heat dissipation qualities are also notable, maintaining consistent performance even during rapid-fire strings.
The primary strength is undoubtedly its ability to deliver consistent, pinpoint accuracy in a lightweight package. The main area for potential improvement would be offering pre-fit options for more rifle platforms. It certainly exceeded expectations and I would buy another one.
