The Difference Between Controlled Round and Push Feed | MidwayUSA Gunsmithing
Larry Potterfield, founder of MidwayUSA, provides an expert demonstration of the key differences between Controlled Round Feed (CRF) and Push Feed bolt action systems. He uses a Mauser 98 to illustrate CRF, where the extractor grips the cartridge rim early, and a Remington 700 for Push Feed, where the extractor engages later. The demonstration highlights the mechanical control each system offers during the feeding and chambering process.
