BSF Barrels Zermatt Origin Carbon Fiber Prefit Barrel 300 Winchester Magnum 20" 1:10" Twist

Overview

The BSF Barrels Zermatt Origin prefit barrel is chambered in 300 Winchester Magnum with a 20-inch length and 1:10-inch twist rate. This barrel is constructed by jacketing a 416R stainless steel match barrel in a roll-wrapped carbon fiber sleeve, which is loaded under tension to maintain straight rifling as the barrel warms. This method utilizes specially designed carbon fiber that matches the expansion rate of stainless steel to prevent delamination. The design features machined openings in the carbon fiber jacket that create air gaps, allowing for faster cooling and reduced weight compared to traditional steel barrels. The carbon fiber sleeve also provides a vibration-dampening effect to promote consistent shot groups. Additional features include 6-groove button rifling, an 11-degree target crown, and a double stress-relieved construction for enhanced stiffness and strength.
