I am new to this forum but have visited often searching for answers. The first photo is of my Wilson Case Gage with no round inserted. The second photo is of a once fired case inserted into the case gage. The second photo shows that the fired cartridge is roughly .006 above recommended SAMMI max. The cases are from new Hornady .223 factory ammunition fired from my AR-15. I checked the head space prior to firing and they were all roughly -.002 below max.
Am I correct to assume that to prolong case life I should adjust my sizing die to bump the shoulders back no more than .004 even though this is above the recommended max? My reloading procedure is to use a Redding body die followed by a Lee neck sizing collet die. I got approximately the same reading on all 50 cases that I checked.
I generally get the same +.006 on rounds fired from my Mini-14.
