I finally got my first grendel build done. I'm using a Larue 18" barrel with matching bolt. I did the break in for the barrel. After that I was shooting Hornady Black 123gr and some Wolf classic 100gr. After I started to wrap things up I noticed some of the wolf steel case was split below the shoulder and a few of the hornady brass was split at the shoulder. Any clue what would cause this?
Now it was pretty cold out. Not sure if this would cause an issue?
Other then that it shot great and group really well with the wolf ammo.
