Unlocking the Potential of Bartlein Barrels - Precision Craftsmanship for Optimal Performance

At Bartlein Barrels, we take pride in crafting high-quality barrels that redefine precision shooting. Our SS (Stainless Steel) 6.5mm Bartlein Barrel, featuring the B#12 Heavy Palma profile, 8 twist rate, 31-inch blank, and 5R rifling, is engineered to deliver unmatched performance and accuracy. Explore the key factors that set Bartlein barrels apart:

Contour Impact on Barrel Performance

Do contours affect barrel weight? Yes, they do. The choice of barrel contour plays a crucial role in determining its weight and performance. Heavier contours provide advantages in terms of stability and resistance to heat-induced wandering of groups/shots during extended shooting sessions. Unlike button-rifled barrels, our single point cut rifling process minimizes stress in the barrel blank, reducing the significance of contour choice.

Do heavier contours shoot better than lighter ones? While heavier barrels often provide enhanced shooting experiences by mitigating recoil and reducing fatigue, lighter contours can also deliver exceptional performance. The impact of contour choice may not be as critical as commonly believed.

Should suppressors be used on any barrel contour? Suppressors are typically more effective when attached to heavier barrels as they influence harmonic vibrations. We recommend avoiding suppressors on barrels smaller than a medium palma contour for optimal performance.

The Advantages of Single Point Cut Rifling

Our commitment to single point cut rifling ensures that our barrels maintain their precision without introducing excessive stress. This method prevents bore size variations and bore opening issues common in button-rifled barrels. Additionally, threading the muzzle for accessories like muzzle brakes or suppressors poses no risk of bore opening, preserving accuracy, especially at the muzzle's crown edge.

Significance of Fluting

Weight: Fluting reduces barrel weight without altering the contour, making it a popular choice for weight-conscious shooters.

Barrel Cooling: Fluting increases the surface area, enhancing heat dissipation, and maintaining consistent performance.

Aesthetic Appeal: Many of our customers choose fluting for its unique visual appeal, adding a distinct look to their barrels.

Questions about Fluting:

Minimum Depth for Fluting: Fluting barrels too deeply can lead to harmonic and vibration issues, potentially impacting accuracy. If you cannot add fluting during barrel selection, it may indicate that the chosen contour is too shallow for fluting.

Effect on Barrel Stiffness: Fluted barrels are generally less stiff compared to their non-fluted counterparts.

Rifling and Its Impact

Choosing Rifling: We offer three rifling types: 4-groove, 5R, and Conventional-5. The number of grooves does not significantly affect accuracy or barrel life, as confirmed by feedback from ammunition and bullet manufacturers.

Additional Benefits of 5R Rifling: 5R rifling minimizes bullet failure due to its gentler angle on the lands, resulting in less deformation to the bullet jacket during the transition from the case into the rifling. It also improves bullet flight, as observed by ammunition and bullet makers.

Exceptions: Some short jacket 6mm bullets used in short-range bench shooting may not perform optimally with 5R rifling due to the rifling's driving effect on these bullets. In such cases, accuracy may be impacted.
