Bartlein Barrels SS .338 Cal B# Custom: Precision Engineering for Elite Performance

Bartlein Barrels: Mastering Precision with the SS .338 Cal B# Custom Barrel

Introducing the Bartlein Barrel SS .338 Cal B# Custom, featuring an 8.5 twist, 36'' blank, and 5R rifling, designed for shooters and custom rifle builders seeking unparalleled precision. Bartlein Barrels, known for their meticulous manufacturing process, emphasizes the critical role of barrel contours, the superiority of single-point cut rifling, and the benefits of fluting in enhancing shooting accuracy and performance.

Understanding the Impact of Barrel Contours

Barrel weight and performance are significantly influenced by contour design. Heavier contours can provide stability and minimize shot wandering caused by heat and residual stress, common in button-rifled barrels. However, Bartlein's advanced single-point cut rifling technique reduces the need for heavier contours by eliminating stress in the barrel, offering flexibility in barrel design without compromising on accuracy.

The Superiority of Single-Point Cut Rifling

Single-point cut rifling, exclusive to Bartlein Barrels, ensures almost perfect concentricity and uniform twist rates, crucial for achieving superior accuracy. This method induces no stress into the barrel, allowing for the production of precision barrels that enhance shooting performance across various disciplines, from competitive shooting to hunting.

The Art and Science of Fluting

Fluting a barrel not only contributes to a unique aesthetic but also plays a functional role in reducing weight and improving barrel cooling. While fluting can potentially affect barrel stiffness, Bartlein Barrels expertly balances these factors to ensure enhanced performance and accuracy without compromise.

Rifling: The Core of Barrel Precision

Choosing the right rifling is crucial for optimal barrel performance. Bartlein offers 4-groove, 5R, and Conventional-5 rifling options, with 5R rifling known for minimizing bullet deformation and improving flight stability. This precision rifling technique has been proven to enhance accuracy, providing a distinct advantage to shooters.
