In this PounderLabs video we focus on identifying and fixing a chamber flaw in a new Lothar Walther drop-in barrel for the CZ 457. We discuss recent history of the CZ 457 MTR, 22 LR rim thickness and headspace measurement and chamber fitment. Detail the repair of the barrel chamber by Pendergraft Gun Works and share our range test results with hits-on-target measurement and comparisons to our other 24” CZ 457 match rifle.
