Bartlein Barrels: Elevating Precision Shooting with Single-Point Cut Rifling

The Science Behind Barrel Contours and Performance

Bartlein Barrels, renowned for precision single-point cut-rifled barrels, addresses common inquiries about the impact of barrel contours on weight and shooting performance. Understanding that heavier contours can mitigate the wandering of shots caused by residual stress, especially in barrels manufactured through button rifling, Bartlein emphasizes that their single-point cut rifling method eliminates this concern, making contour selection a matter of preference rather than necessity for maintaining accuracy.

Enhancing Shooting Accuracy with Heavier Contours

Heavier barrels contribute to better shooting experiences by aiding in recoil management and reducing shooter fatigue, potentially leading to improved accuracy over prolonged shooting sessions. However, Bartlein's experience shows that lighter contours can perform just as well, if not better, underscoring the less critical nature of barrel weight on overall shooting accuracy.

Suppressor Considerations and Barrel Contours

When attaching suppressors, Bartlein recommends opting for no less than a medium palma contour to accommodate the harmonic variations induced by the added weight of the suppressor, ensuring optimal barrel performance and accuracy.

Single-Point Cut Rifling vs. Button Rifling

Bartlein Barrels' preference for single-point cut rifling over button rifling stems from the former's ability to maintain consistent bore sizes without inducing stress that can negatively affect accuracy. This method ensures that Bartlein barrels remain unaffected by the common issues associated with button rifling, such as bore enlargement due to contour reduction or muzzle threading.

The Importance and Benefits of Barrel Fluting

Barrel fluting offers multiple advantages, including weight reduction, enhanced barrel cooling, and aesthetic appeal. While fluting can slightly affect barrel stiffness, Bartlein maintains that the overall impact on performance is minimal, with the primary focus on creating barrels that excel in precision and longevity.

Choosing the Right Rifling: The Advantage of 5R

Bartlein's 5R rifling, known for its gentler land angles and uneven number of lands, minimizes bullet deformation, enhancing bullet flight and reducing the likelihood of bullet failure. This rifling style is particularly beneficial for most bullet types, with specific exceptions noted for short jacket 6mm bullets used in short-range bench shooting.

Why Choose Bartlein Barrels?

For competitive shooters, hunters, and precision enthusiasts, Bartlein Barrels offers a commitment to quality, performance, and innovation. Through advanced manufacturing techniques and a dedication to excellence, Bartlein ensures that each barrel enhances your shooting experience, pushing the boundaries of accuracy and reliability.
