[QUOTE="bigedp51, post: 1384205, member: 28965"] Out of all the headspace gauges I have there is only .003 between the GO and NO-GO gauge. And this is for setting up new or re-barreled rifles and the SAAMI cartridge and chamber diagrams show .010 between minimum and maximum headspace. And when people collect 30 or more older type milsurp rifles they need a simple and less costly method of checking headspace. Military headspace on a Enfield rifle is .064 minimum and .074 maximum. And SAAMI headspace is .064 GO and .067 NO-GO for initial headspace setup. Below my .303 British Headspace gauges, with SAAMI and military gauges. So do not tell me there is something wrong with using the primer method to check headspace/head clearance. [IMG]https://www.milsurps.com/images/imported/2009/08/IMGP5264-1.jpg[/IMG] And even if these older rifles exceed maximum headspace if the cases are fire formed to the chamber they can be safely fired with reasonable loads. And this posting is about a rifle that a so called gunsmith screwed up re-barreling and gave it back to the owner grossly out of headspace limits. And again if this person had used the primer method I described he would have seen how much head clearance the rifle had. Below using the primer method on a Enfield rifle grossly out of headspace limits. And the amount the primer is protruding is the amount of head clearance this rifle had. And the amount of head clearance should be equal to the amount of shoulder bump. Meaning on a bolt action rifle .001 to .002 to insure the case does not stretch beyond its elastic limits. [IMG]https://www.milsurps.com/images/imported/2009/10/9-1.jpg[/IMG] So again headspace is also the distance between your ears and how you use this space. [/QUOTE]
