Ok, in a nutshell I am using an NOE 22-55 clone mould and loading for my AR. I previously loaded some of these gas checked/aloxed boolits and had lots of problems until I found out I was stretching the shoulder out when pulling the case out of my sizing die. I then bought a case gauge...and resized a few of those(with the decapping pin out), and they passed the case gauge and then shot well.
That was some time ago and now I am pc'ing everything and I loaded some up, and they passed the case gauge test. Loaded them into the gun and a couple fired but most did not! On my pc was distinct marks from the lands. It appears that the cartridge was not fully chambered since the primer had no markings whatsoever...but it passed the case gauge?!?!?!
I'm almost going to quit reloading for my AR. I think I can get the ammo to work but it takes way too much time to get to that point...
Any ideas?
