Bartlein Barrel - SS, 6mm, B#9 Heavy Varmint

Explore the world of precision shooting with Bartlein Barrel's stainless steel 6mm B#9 Heavy Varmint barrel. Learn how various factors, including barrel contours, rifling, and fluting, influence the performance of your rifle.

Do Contours Affect Barrel Weight?

Yes, barrel contours do affect weight. Heavier contours can have advantages, especially when it comes to resisting barrel movement caused by heat during prolonged shooting sessions. Bartlein Barrels employs single point cut rifling, reducing stress on the barrel blank, making the contour less critical compared to button-made barrels.

Does Contour Affect How a Barrel Shoots?

Indeed, contour plays a role in a barrel's shooting performance. Heavier barrels can improve stability, recoil control, and endurance for shooters, allowing for more rounds to be fired over extended periods. However, lighter contours can also deliver exceptional results, challenging the belief that heavier is always better.

Should Suppressors Be Put on Any Barrel Contour?

No, suppressors are best suited for heavier barrel contours. Adding a suppressor affects the harmonic vibrations of the barrel, making it more suitable for medium palma contours or larger.

Why Is Single Point Cut Rifling Better Than Button Rifling?

Single point cut rifling, as used by Bartlein Barrels, reduces stress on the barrel blank, ensuring consistent bore sizes and preventing bore opening issues, especially at the muzzle crown. Button rifling can lead to bore size changes, affecting accuracy.

Why Is Fluting a Barrel Important?

Barrel fluting serves several purposes:

• Weight Reduction: Fluting removes material from the barrel without altering its contour, reducing overall weight.
• Barrel Cooling: Increased surface area from fluting allows for better heat dissipation during extended shooting sessions.
• Aesthetic Appeal: Fluting adds a unique and attractive look to the barrel, enhancing its visual appeal for many shooters.

However, it's essential to avoid excessive fluting depth, as it can lead to harmonic and vibration issues, potentially impacting accuracy.

Why Is the Rifling on a Barrel Important?

The style of rifling can significantly impact a barrel's performance. Bartlein Barrels offers 5R rifling, which offers several advantages:

• Deformed Bullet Reduction: The gentler angle of 5R rifling reduces bullet deformation, leading to improved bullet stability and accuracy.
• Enhanced Bullet Flight: 5R rifling helps maintain bullet stability during flight, contributing to better downrange performance.

While 5R rifling is generally beneficial, it's essential to consider exceptions, such as short jacket 6mm bullets that may perform better with other rifling styles.
