Unlocking the Precision of Bartlein Barrels - Choosing the Right Features for Superior Performance

At Bartlein Barrels, we are dedicated to crafting barrels that elevate your shooting experience. Our SS (Stainless Steel) 7mm Bartlein Barrel, featuring the B#11 Medium Palma profile, 9 twist rate, 31-inch blank, and 4 Groove rifling, offers a range of features that impact your shooting performance. Let's explore the key considerations:

Contour Influence on Barrel Weight

Do contours affect barrel weight? Absolutely, they do. The choice of barrel contour plays a pivotal role in determining its weight and how it performs. Heavier contours provide stability and resist barrel movement when it gets hot, ensuring your shots stay on target. Unlike button-rifled barrels, our single point cut rifling process minimizes stress, making contour selection less critical.

Do heavier contours shoot better than lighter ones? While heavier barrels can improve shooting by reducing recoil and fatigue, lighter contours can perform exceptionally well. The impact of contour choice may not be as crucial as commonly believed.

Should suppressors be used on any barrel contour? No, suppressors typically work better on heavier barrels, as they can influence harmonic vibrations. We recommend avoiding suppressors on barrels smaller than a medium palma contour for optimal results.

Advantages of Single Point Cut Rifling

Our commitment to single point cut rifling ensures precision without introducing undue stress. Unlike button-rifled barrels, our method avoids bore size variations and opening issues. Whether threading the muzzle for accessories or preserving accuracy at the muzzle's crown edge, our barrels excel.

The Significance of Fluting

Weight: Fluting reduces barrel weight while preserving the contour, appealing to weight-conscious shooters.

Barrel Cooling: Fluting increases surface area, enhancing heat dissipation for consistent performance.

Aesthetic Appeal: Many customers choose fluting for its unique visual enhancement, adding character to their barrels.

Questions about Fluting:

Minimum Depth for Fluting: Excessive fluting can lead to harmonic and vibration issues, impacting accuracy. If you can't add fluting during barrel selection, it may indicate the contour is too shallow.

Effect on Barrel Stiffness: In general, fluted barrels are less stiff compared to non-fluted ones.

Rifling's Role in Barrel Performance

Choosing Rifling: We offer three rifling types: 4-groove, 5R, and Conventional-5. The number of grooves has minimal impact on accuracy or barrel life, validated by feedback from ammunition and bullet manufacturers.

Additional Benefits of 5R Rifling: 5R rifling minimizes bullet failure due to its gentler angle on the lands, reducing deformation during bullet transition. It improves bullet flight, as affirmed by ammunition and bullet makers.

Exceptions: Some short jacket 6mm bullets used in short-range bench shooting may not perform optimally with 5R rifling. This exception may affect accuracy.
