Not sure who I copied the vid from, but thanks!


when you have it right the case touches the back of the bolt and the front of the chamber, keeping the case from sliding and only allows expansion which fills in the chamber space forming the new case.


this video shows a case being fired with to much headspace.


If you have to much headspace, you can see where the primer moves back first and then the case follows. you can also see where the case get thin just above the web and the next reload will result in cracks and separation.
