[QUOTE="Willys46, post: 214401, member: 6536"] [b]Not a Gunsmith[/b] I am not a gunsmith but like others will take a stab at it. I am sure one of the good gunsmiths on here with correct us. For my simple mind. i think of headspace as the distance from the bolt face to the center line of the shoulder for non belted cases. The belted cases are headspaced off the belt for SAAMI specs. but most people after the first firing of new brass headspace there reloads off the boltface. Too much headspace will allow the shoulder of the ammo to move to much and cause case head seperation. This is the resaon for a unsafe gun that has too much head space. Even if you do not get case head seperation, when you resize your brass you are over working it causing it to strech and get brittle. To little headspace and a round will not chamber..Just like when you reload a piece of brass and it becomes difficult to close the bolt. You need to push back the shoulder .002 or so, to allow it to chamber. I hope this helps. [/QUOTE]
