[ARCHIVED THREAD] - Bent cases ,, cause??

Posted: 2/11/2013 1:21:26 PM EDT

I finally got my 6.8 out to the range and she exceeded my expectations. However, I noticed about 80% of the cases had a dent at the mouth of the case. I have never seen this before. 16" barrel, carbine length gas tube, adjustable gas block, and full auto bolt. Anyone know the cause?.

Bottom looks good:

5 shot grouping is good.

Mouth sports a dent.

The extractor might have to much tension on the case and trying to eject the case out of the chamber and clear the ejection port to soon.

This. It's no big deal, dent like that will come right out when the case is resized.
