[QUOTE="J E Custom, post: 1409804, member: 2736"] First, Primers are not used to set head space and should always be seated flush or below the case head. when the cartridge is fired, the first thing to move is the case and it moves back to the bolt face the amount of the head space (.000 to .003)thousandths The primer doesn't move it is compressed causing it to flatten (One of the signs of pressure) The inside of the primer will move back however much it can based on pressure but the face of the primer never exceeds beyond the cartridge face. (the bolt face will not let it). Over sizing the cases only cause case stretch and the primer will never be sticking out of the case head after firing. Over sizing is variable based on the reloaders requirements and beliefs. If ease of loading is the priority, more sizing may be the norm. If case life and wear and tear on equipment is the priority less sizing is the norm. J E CUSTOM [/QUOTE]
