This video demonstrates the process of relining a pitted .22 rimfire rifle barrel, specifically a Remington Rolling Block No. 4. Larry Potterfield details the disassembly, precise drilling of the old barrel, installation of a new liner using Loctite 680, chambering with a .22 LR reamer, and checking headspace. The process concludes with crowning the muzzle, filing the extractor slot, applying cold blue, and electrochemically marking the barrel for historical record.
