Do Contours Affect Barrel Weight and Performance?
Understanding the influence of contours on a barrel's weight and performance is crucial for precision shooters. The Bartlein Barrel's design integrates the specific needs of shooters, offering a balance of weight and stability. Heavier contours, common in button-made barrels, can resist movement as the barrel heats up, maintaining accuracy over extended shooting sessions. However, Bartlein Barrels, with their single point cut rifling, minimize stress, making contour choice less critical.
The Superiority of Single Point Cut Rifling
Bartlein BarrelÕs choice of single point cut rifling over button rifling is a testament to their commitment to accuracy and quality. This technique avoids the stress and potential bore size changes that button rifling can induce, particularly in lighter weight contours. This meticulous approach ensures consistent bore sizes and enhances long-term accuracy, crucial for precision shooting.
Fluting: More Than Just Aesthetics
Fluting a barrel is not just about aesthetics; it plays a significant role in performance. By removing material, fluting reduces weight without altering the contour. It also increases the surface area for better heat dissipation. However, excessive fluting can lead to harmonic and vibration issues, which Bartlein Barrel carefully avoids to maintain accuracy.
The Advantages of 5R Rifling
Bartlein BarrelÕs use of 5R rifling is a notable feature. This rifling style, with its gentler land angles and odd number of lands, minimizes bullet deformation, reducing bullet failure and improving flight. The unique configuration of 5R rifling makes it highly effective for most bullets, though short jacket 6mm bullets used in short-range bench shooting may perform differently due to their short bearing surface.
