Finally ready to shoot my Grendel and zero my scope. I was shooting factory Hornday 123 A-max. I a have a Syrac adjustable gas block so I needed to adjust that too. I fired one round until the bolt would lock back. Once it did that I opened it a half turn more. During this progression I noticed the case mouths started to get dented or bent when they were ejected. Is this normal for the Grendel?
Also I was using an Alexander Arms 10 round magazine. I noticed the follower wouldn't always catch the bolt stop and push up to lock the bolt back. Compared to another magazine AR-Stoner that I have the AA mag has more play in the follower forward and backwards. If the follower is pushed forward in the mag the bolt stop won't be caught and the bolt closes. I think its a bad magazine. I have 2 more AR-Stoner mags to compare to, but haven't fired them in the gun yet.
