Explore the Bartlein Barrel: Precision and Performance

When it comes to choosing the right barrel for your firearm, there are several factors to consider. Bartlein Barrels, known for their exceptional quality and craftsmanship, provides answers to some of the most common questions about barrels and how they impact your shooting experience.

Do Contours Affect the Barrel Weight?

Yes, the contour of a barrel does affect its weight. In general, a heavier contour barrel will resist movement and wandering as it heats up during prolonged shooting sessions. However, it's essential to note that the impact of contour weight can vary depending on factors like residual stress and barrel manufacturing methods.

Does Contour Affect How a Barrel Shoots?

Yes, the contour of a barrel can influence shooting performance. A heavier barrel provides stability, reduces recoil, and allows for more extended shooting sessions with less fatigue. While a heavier barrel is generally preferred, there are exceptions where lighter contours can perform exceptionally well.

Should Suppressors Be Put on Any Barrel Contour?

No, suppressors should be carefully selected based on barrel contour. Suppressors can affect the harmonic vibrations of the barrel, and for optimal performance, they are best suited for heavier contours like the medium palma contour.

Why Is Single Point Cut Rifling Better than Button Rifling?

Single point cut rifling, as used by Bartlein Barrels, is superior to button rifling because it doesn't induce stress into the barrel blank. Button rifling can cause bore size changes, particularly as contours become smaller. This issue is less prevalent with single point cut rifling, ensuring consistent accuracy. Additionally, threading the muzzle for muzzle brakes or suppressor attachment is more stable with single point cut rifling.

Why Is Fluting a Barrel Important?

Fluting a barrel offers several advantages:

• Weight Reduction: Fluting removes material from the barrel without altering the contour, reducing overall weight.
• Barrel Cooling: Fluting increases the surface area, allowing for better heat dissipation.
• Aesthetic Appeal: Fluting adds a unique and attractive look to the barrel.

Questions about Fluting:

Do We Have a Minimum Depth for Fluting? Fluting can be taken too deep, potentially causing harmonic and vibration issues, leading to accuracy problems. If fluting isn't available for a particular barrel, it may indicate that the contour is too shallow.

Does Fluting Make the Barrel Stiffer? Fluting typically reduces barrel stiffness compared to an identical non-fluted barrel.

Why Is the Rifling on a Barrel Important?

What Style Rifling Should I Get?

Bartlein Barrels offers three rifling types: 4-groove, 5R, and Conventional-5. The style or number of grooves doesn't significantly impact accuracy or barrel life. The 5R rifling style has the added benefit of reducing bullet failure due to its gentler angle on the lands and grooves. It deforms the bullet less when it transitions from the case to the rifling, improving performance.

Additional Benefits of 5R Rifling: 5R rifling has been found to enhance bullet flight and reduce bullet failure. However, some exceptions exist, such as short jacket 6mm bullets, which may not perform optimally with 5R rifling.

Choosing the right barrel and rifling for your firearm is crucial for achieving your desired shooting performance. Bartlein Barrels' commitment to quality and precision ensures that you have the information you need to make the best choice for your needs.
