Understanding Barrel Dynamics with Bartlein Barrels

At Bartlein Barrels, we specialize in crafting stainless steel barrels like our 6mm B# Custom, featuring a 7 twist, 31'' blank, and 5R rifling, designed for unparalleled shooting performance. Dive into the science of our barrels and how we optimize every aspect for accuracy and precision.

Does Contour Affect Barrel Performance?

Yes, barrel contour impacts weight and heat resistance. Heavier contours can reduce the effect of heat and stress, maintaining accuracy over continuous shooting sessions, especially in barrels where residual stress is present. However, Bartlein's single-point cut rifling minimizes stress, making contour choice more flexible based on shooter preference and application.

The Importance of Fluting

Fluting enhances a barrel in three key areas: weight reduction, improved cooling, and aesthetics. By removing material, fluting lightens the barrel without compromising its structural integrity, increases surface area for faster heat dissipation, and adds a distinctive look to your firearm.

Rifling: The Heart of Precision

Rifling style, whether 4-groove, 5R, or Conventional-5, generally does not affect accuracy or barrel life significantly. However, 5R rifling offers advantages in bullet integrity due to its gentler land angles and asymmetric land layout, contributing to enhanced bullet flight and reduced deformation.

Choosing the Right Barrel

When selecting a barrel, consider factors like the intended use, weight preferences, and the benefits of different rifling styles. Bartlein Barrels provides options tailored to your needs, ensuring top performance whether for competitive shooting, hunting, or precision projects.
