Zediker is known as an early ambassador for using accurized M16s in service rifle competition, but he is vastly experienced with and still a proponent of the M14/M1A. I also relied heavily on Glen Zediker's publication Reloading for the Match M14. To help answer the question, I turned to Hodgdon's propellant guru Ron Reiber and Hornady's lead cartridge design engineer, and vintage rifle savant, Dave Emary.
M14 STOCK CRACK CRACK
Operating rods bend, parts crack and break. However, if you load the Garand with a slow-burning powder, the pressure peak occurs later and lasts longer - resulting in significantly higher pressures flowing through the gas port and into the operating system. With appropriate powder, the pressure peak occurs early and drops off well before the bullet passes the gas port. These cyclic rates are achieved by using medium burn-rate propellants such as the various 4895s. This rifle was designed to function within a specific cyclic parameter. If that's the case, he asked, why is there no such caveat for the M1A?įor starters, yes, slow-burning powders can be dangerous in the M1 Garand. He pointed out that many articles caution against using some powders in the M1 Garand because doing so can bend the operating rod. While the M1A is less susceptible to damage from improper reloading than the M1 Garand, using the wrong propellants can still stress your rifle.Ī reader of our magazine recently asked us about loading for the M1A.
