[QUOTE="J E Custom, post: 1695945, member: 2736"] Ideally, Primers are flush and against the bottom of the primer pocket so there is little if any movement when the firing strikes it or pressure moves it. If it is slightly below flush, There will be some movement and sometimes this breaks the seal and causes primers to leak damaging the bolt face when high pressure loads are used. A few thousandths below flush wont normally cause any problems as long as High Pressure loads (65,000 + PSI) are not used and only subtracts from the total amount of firing pin strike. if the firing pin strike is set up to be .055 thousandths you can subtract the 5 or 6 thousandths from the .055 for the theoretical travel. If the firing pin is set to the minimum, with the primer being low, it mite cause misfires. so if your firing pin is .055 to .065 you should not have a problem. J E CUSTOM [/QUOTE]
