Bartlein Barrels: Elevating Shooting Precision

Understanding Barrel Contours

Barrel contours play a crucial role in firearm accuracy and performance. Heavier contours can mitigate the barrel's tendency to shift or "wander" during firing sequences, especially as it heats up. This phenomenon is often observed in barrels with residual stress, a common trait in those produced via button rifling. However, Bartlein Barrels, crafted with single point cut rifling, do not introduce such stress, making contour choice less critical for our precision barrels.

The Significance of Barrel Weight and Contour

A heavier barrel typically offers better shooting performance by aiding in recoil management and reducing shooter fatigue. This allows for more consistent firing over extended periods. Yet, it's important to note that lighter contours can also achieve exceptional accuracy, challenging the conventional preference for heavier barrels.

Suppressors and Barrel Contours

Not all barrel contours are suitable for suppressor attachment. Heavier barrels, such as those with a medium palma contour or larger, are better suited to accommodate suppressors. This is due to the suppressor's influence on barrel harmonics and vibration, which can enhance shooting performance.

The Advantages of Single Point Cut Rifling

Single point cut rifling, exclusive to Bartlein Barrels, offers superior accuracy and longevity over traditional button rifling methods. This technique ensures minimal stress on the barrel, preserving bore integrity and enhancing performance, especially in lighter contours and when threading for muzzle devices.

Why Choose 5R Rifling?

Bartlein Barrels' 5R rifling is designed to minimize bullet deformation, thereby reducing bullet failure and improving flight stability. The unique geometry of 5R rifling, with its gentler land-to-groove transitions and odd number of lands, ensures less distortion to the bullet jacket. This rifling style has been proven to enhance performance, except in specific cases with short jacket 6mm bullets used in short range bench shooting.

Barrel Fluting: More Than Aesthetic Appeal

Fluting a barrel not only adds to its aesthetic appeal but also reduces weight, improves cooling, and can impact the barrel's vibrational characteristics. However, the depth of fluting must be carefully considered to avoid compromising barrel integrity and accuracy.

Conclusion

Bartlein Barrels stands at the forefront of barrel manufacturing, offering shooters unparalleled precision and performance. Our dedication to quality, from single point cut rifling to the innovative 5R rifling, ensures that every barrel meets the highest standards of accuracy and durability.
