Understanding Barrel Contours and Weight

At Bartlein Barrels, we address a common query: Do contours affect barrel weight? The answer is a definitive yes. Barrel contours play a crucial role in determining the overall weight and balance of the firearm, impacting performance, especially in precision shooting scenarios.

Comparing Heavier and Lighter Contours

Many shooters question whether heavier contours shoot better than lighter ones. It's important to note that residual stress, common in button-made barrels, can lead to accuracy issues as the barrel heats up. Our heavier contour barrels resist this movement, offering more stable performance. However, our unique single point cut rifling process eliminates this stress, making the contour choice less critical than in button-made barrels.

The Effect of Contour on Shooting

A heavier gun, due to a heavier barrel, typically offers better shooting experience by aiding in recoil management and reducing shooter fatigue. That said, we've seen excellent performance from lighter weight contours as well, challenging the belief that heavier always means better.

Suppressors and Barrel Contours

When it comes to mounting suppressors, we recommend avoiding smaller than medium palma contours. A suppressor adds weight, affecting the harmonic vibrations of the barrel, and thus its shooting performance.

Advantages of Single Point Cut Rifling

Unlike button rifling, our single point cut rifling doesn't induce stress into the barrel, maintaining consistent bore sizes and enhancing overall accuracy, especially critical for threading applications like muzzle brakes or suppressors.

Why Fluting Matters

Fluting serves multiple purposes: reducing barrel weight, increasing surface area for better cooling, and adding aesthetic appeal. However, overly deep fluting can impact barrel harmonics and accuracy. Our expertise ensures optimal fluting depth for balanced performance.

Choosing the Right Rifling Style

We offer various rifling styles, including 4-groove, 5R, and conventional-5. The style or number of grooves doesn't significantly impact accuracy or barrel life, as evidenced by extensive testing and feedback from ammunition and bullet manufacturers.

Benefits of 5R Rifling

The 5R rifling is particularly effective against bullet failure due to its gentler land angles and the odd number of lands, resulting in less bullet deformation. This style has been shown to improve bullet flight, an insight gained from ammunition experts in 2019.
