PROOF BBL CF BLANK BOLT .308 SENDERO LT 20 1-10 Review

The PROOF BBL CF BLANK BOLT .308 SENDERO LT 20 1-10 Made a Bold First Impression

The PROOF BBL CF BLANK BOLT .308 SENDERO LT 20 1-10 represents a commitment to precision and lightweight performance in a rifle build. Coming from PROOF Research, a company renowned for their carbon fiber barrels, this blank bolt barrel promises exceptional accuracy and reduced weight, perfect for custom .308 builds aimed at hunting or long-range shooting. I was immediately drawn to this barrel because I’ve been planning a lightweight .308 build for a backcountry elk hunt.

My old rifle, while reliable, felt like lugging around an anchor after a few days in the mountains. I needed a solution that shaved off weight without sacrificing accuracy – a critical factor for ethical hunting at longer distances. The PROOF barrel’s carbon fiber construction seemed like the ideal answer, promising both weight reduction and improved heat dissipation.

The initial unboxing was impressive. The barrel arrived meticulously packaged, showcasing PROOF Research’s attention to detail. Holding the barrel for the first time, I was struck by how light it was – noticeably lighter than any steel barrel I’ve handled in this caliber. The carbon fiber weave looked flawless, and the overall build quality exuded precision.

I considered a couple of other options, including a steel fluted barrel from another reputable manufacturer and a similar carbon fiber offering from a competitor. However, the PROOF barrel’s reputation for accuracy, combined with its Sendero Light contour, ultimately swayed my decision. I was hoping for a rifle build that handled easily and shot accurately, and the PROOF BBL CF BLANK BOLT .308 SENDERO LT 20 1-10 seemed to deliver on both fronts.

My first impression was definitely one of excitement. The barrel’s lightweight design and promise of superior accuracy ignited my enthusiasm for the upcoming build. I couldn’t wait to see how it would perform in the field.

Real-World Testing: Putting PROOF BBL CF BLANK BOLT .308 SENDERO LT 20 1-10 to the Test

First Use Experience

I tested the PROOF BBL CF BLANK BOLT .308 SENDERO LT 20 1-10 during several range sessions and a weekend hog hunt in central Texas. The range sessions involved load development and zeroing at distances from 100 to 600 yards. The hog hunt provided a more practical test under field conditions.

The rifle performed exceptionally well at the range, maintaining sub-MOA accuracy with several different handloads. Even during rapid firing strings, the barrel exhibited minimal heat-related POI shift. The hog hunt offered a different challenge. The damp, cool conditions of the early morning proved no obstacle to the rifle’s reliability, and I was able to harvest two hogs with precise shot placement at moderate distances.

The barrel proved easy to work with during the build process, requiring minimal gunsmithing adjustments. I did need to familiarize myself with carbon fiber barrel cleaning procedures, as they differ slightly from those used for traditional steel barrels. There were no unexpected issues after the first use, only confirmation that my initial excitement was warranted.

Extended Use & Reliability

After several months of consistent use, the PROOF BBL CF BLANK BOLT .308 SENDERO LT 20 1-10 continues to impress. The barrel’s accuracy has remained consistent, and there are no visible signs of wear and tear on the carbon fiber wrap. Regular cleaning and proper storage have ensured its continued performance.

The barrel shows no signs of degradation, even after being subjected to varying temperatures and conditions. Maintenance involves using a bore guide and carbon fiber-safe cleaning solutions to prevent damage. Compared to my previous steel-barreled .308, the PROOF barrel outperforms it in both accuracy and weight reduction, making it a significant upgrade.
