Ok. I checked bolt (from first 2018 group buy). Overall length is 2.814. Bolt recess is .134 instead of .136. Within tolerances?
Firing pin length is 3.278 and I have pin protrusion of .0305.
Upon disassembly, I found an excessive amount of oil and carbon. I would like to think this, combined with the below freezing temperatures, slowed it down enough to not ignite the primer.
But that doesn't explain the 2 misfires during the initial function testing in late summer. However, I believe they were early on with a very low round count and these group buy bolts are tight in the carrier.
Any other thoughts?
BTW, all factory ammo. Inthinknthe initial two were with Wolf steel case. The others more recently were with Federal Fusion.
