went to the range today to play with a new eotech. since, i also just picked up a wci brake for the grendel......I figured I play with both toys at the same time today. So , I mounted the eotech to my AA Tactical 16 upper and headed to the range.
Since I was only going to be shooting at up to 100 yds max, I figured I shoot up the cheaper wolf MPT stuff rather than my hornady amax supply.
I have had issues with the wolf ammo in the past so I figured I take a sheridan case gauge with me. In the past, I have have had about 10% of the wolf ammo wolf the primers out of the case. I have also had a few cases that never ejected.....I think they would come off of the bolt during the reward action of the bolt cycle.
So...........today was the worst day ever with the wolf ammo. I shot 60 rounds, had 6 cases blow the primers out, had 8 stovepipe partial ejections, had 5 cases got stuck and slammed into the ejection port of the upper (totally deformed the case mouth of each case), and had a few more case that never ejected from the upper and just jammed up the operation!
I checked alot of the cartidges before loading them in the magazines. I would drop them into the Sheridan gauge. They all sat a few thousandths below the "minimum headspace" slot that is cut into the face of the sheridan gauge. After firing, they were prefectly fired formed and measured to be perfect in the sheridan gauge.
So, does this sound like purely an ammo issue with wolf or does it sound like a problem with my upper? The bad ejection problems makes we wonder if I have an issue with my extractor. I have examined many of the cases and have noticed that the primers on the unfired wolf ammo are slightly recessed in the case head. ALL of the fired cases have primers that all flush with the case head. Is that normal? I have never inspected fired cases much before this. Also, most of the cases have strong heavy ejector marks on the case heads and some even have extractor swipe marks where there is a bit of peeled back brass on the cases heads.
I'm curious to here what you guys think about this.
