I'm running out of things to check, so next time try three different brands of ammo- in addition to your WWB!

There must be a reason!

Progress! First let me say thank you for your continued help. I was looking through my range bag and found 2 more 9mm Shells, the Luger is my only 9mm gun. I can't tell how old they are but they have to be from within the last month, and the only changes I've made in that time are replacing the main, striker and extractor springs plus the ejector.

Looking at the shells you can see some obvious marks on the side. Looking at the top view picture you can see there is an indent on one of the sides. Could this be a head space issue? How do I check head space?
