Do Contours Affect Barrel Weight and Performance?

Yes, contours do affect barrel weight and performance. A heavier contour barrel can resist movement and wandering as it heats up during prolonged shooting sessions. However, the importance of contour varies based on factors such as barrel stress and shooter comfort.

Should Suppressors Be Used with Specific Barrel Contours?

Yes, suppressors can impact barrel performance. When using a suppressor on a heavier barrel, it can enhance stability. Bartlein Barrels recommends not using suppressors on contours smaller than a medium palma contour to maintain optimal accuracy.

Why is Single Point Cut Rifling Better than Button Rifling?

Bartlein Barrels exclusively utilizes single point cut rifling, which minimizes stress on the barrel blank compared to button rifling. Single point cut rifling also avoids bore size changes, making it ideal for threading the muzzle without compromising accuracy.

Exploring the Benefits of Fluting a Barrel

Fluting a barrel reduces weight without altering its contour, enhances barrel cooling by increasing surface area, and adds an attractive aesthetic dimension to the barrel. Care should be taken not to flute too deeply to avoid harmonic and vibration issues.

Understanding the Significance of Rifling on a Barrel

What Style of Rifling Should You Choose?

Bartlein Barrels offers three types of rifling: 4-groove, 5R, and Conventional-5. The number of grooves does not significantly affect accuracy or barrel life. However, 5R rifling with its gentle lands' angles has been known to help fight bullet failure and improve bullet flight.

While 5R rifling benefits most bullet types, short jacket 6mm bullets may not perform as well with this rifling style. Their short bearing surface and the "R" style of rifling can lead to less consistent results.
