Bartlein Barrels - Elevate Your Shooting Experience

Discover Bartlein Barrels, where precision meets performance. Our stainless steel barrels are designed to enhance your shooting capabilities, tailored to the 7mm Caliber enthusiasts. Learn how different factors, including barrel contours and rifling, can influence your shooting experience.

Do Contours Affect Barrel Weight?

Yes, barrel contours do affect weight. Heavier contours provide stability and help resist barrel movement when it heats up during extended shooting sessions.

Do Heavier Contours Shoot Better?

Heavier contours can contribute to improved shooting performance due to added weight, reducing recoil and shooter fatigue. However, lighter contours can also deliver exceptional results, challenging the belief that heavier is always better.

Should Suppressors Be Used on Specific Barrel Contours?

No, suppressors should not be used on any barrel contour. Heavier barrels typically perform better with suppressors as the added weight affects barrel harmonics. We recommend avoiding suppressors on barrels smaller than a medium palma contour.

Why is Single Point Cut Rifling Superior to Button Rifling?

At Bartlein Barrels, we exclusively use single-point cut rifling to avoid introducing stress into the barrel blank. Button rifling, common in other barrels, can negatively affect bore sizes and consistency, especially with smaller contours. Single point cut rifling eliminates these issues and maintains precision.

Why is Fluting a Barrel Important?

Fluting offers several advantages:

• Weight Reduction: Fluting removes material without altering the contour, reducing overall weight.
• Barrel Cooling: Increased surface area from fluting enhances heat dissipation during firing.
• Aesthetic Appeal: Fluting adds a unique and attractive look to the barrel.

Fluting depth should be carefully considered to avoid harmonic and vibration issues that may affect accuracy.

Why is Rifling Style Important?

Rifling style plays a role in performance. Bartlein Barrels offers three types of rifling: 4-groove, 5R, and Conventional-5. While the number of grooves doesn't significantly impact accuracy or barrel life, 5R rifling is known to reduce bullet failure due to its gentler lands and improved deformation resistance.

Additional Benefits of 5R Rifling

5R rifling benefits include improved bullet flight and reduced deformation. While highly effective for most bullets, some exceptions exist, such as short jacket 6mm bullets used by short-range bench shooters.
