WWSD: Pencil barrel Stress & Heat Zero Testing
This video details a test of modern stress-relieved pencil barrels against the historical concern of heat-induced zero shift. Expert analysis from InRangeTV demonstrates that modern manufacturing techniques significantly mitigate this issue, with Faxon barrels showing minimal shift compared to a vintage Colt SP1. The testing methodology provides valuable insights for rifle builders and shooters concerned with lightweight barrel performance under stress.
