In this episode, Caylen Wojcik sits down with Frank Green of Bartlein Barrels—one of the premier precision barrel manufacturers in the country and a lifelong shooter with roots in high power rifle competition dating back to the late 1980s. Frank traces his path from competitive shooting and gunsmithing to co-founding Bartlein Barrels in 2004, where the team brought single-point cut rifling into the modern era with CNC-controlled precision. This is the first installment of a multi-episode series, and Frank breaks down the fundamentals every shooter should understand about how barrels are made—covering cut rifling, button rifling, hammer forging, and broach cutting—and why no shortcut in barrel manufacturing goes unpunished.

Caylen and Frank dig into the details that matter most for long-range precision: residual stress in barrel blanks, what to look for as your barrel ages, the truth about cold bore shots, and how heat, mirage, and optical illusions can shift your point of impact by several minutes of angle without you ever touching the gun. Frank also walks through his personal cleaning protocol—what products to use, what to avoid, and why using a brush with abrasive compounds is one of the fastest ways to ruin an otherwise excellent barrel. Members of the MDS Club can also catch Frank in the exclusive Fireside Chat episode, where he takes direct questions from the community.
