This guide details the process of building a custom 25 ACP barrel for a Thompson Center Contender. It involves using a specialized Lothar Walther barrel blank, precise drilling with an aircraft drill, chambering with a 25 ACP reamer, and finishing with muzzle crowning. The project aims to create a unique, scoped 25 ACP Contender, potentially exceeding the length of existing custom barrels.

This guide, presented by experts from Brownells, addresses the myth of easily fixing AR-15 headspace issues. While short headspace might be minimally adjustable on certain barrels with a reamer, long headspace requires complex gunsmithing. The video emphasizes that for most users, the cost and difficulty of these repairs make replacing the barrel a more practical solution.

This video details the specifications and usage of Climber brand chamber reamers from Brownells. It highlights their construction from M7 high-speed steel, featuring six straight right-hand cutting flutes designed to resist chatter. The reamers have solid pilots, integral throats, and specific shank and drive sizes, with exceptions for rimfire models. The distinction and application of rougher and finish reamers are explained, emphasizing the rougher's role in saving wear on the finish reamer for high-volume chambering.
