Thanks for the responses guys!
First off, yes I am shooting reloads. I do all my own loading and my rifle has never seen a factory round. I am running 123gr Amaxes over 26gr of 8208 with CCI 450 primers for a COL of 2.250. Shouldn't be overpressure as it's towards the low end of the data according to Hodgdon, and the primers are reading good. I weigh each charge individually on a Redding No. 2 beam so shouldn't be much inconsistency.
As far as the buffer goes, I was also under the impression that the Spike's buffer would be plenty for the Grendel mid length.
I have not seen any signs of leakage around the gas block, but what I did notice upon further inspection is that all three of my gas rings were in perfect alignment. Doh! Don't know if that's the whole problem, but is certainly a good start.
The gouges on the rims of my cases are being caused by what I think is a couple of sharp points at the ends of the radius. It is indeed in need of a little tuning. Is it acceptable to smooth these out with a file of some type or will I run into issues with the extractor not properly gripping the rim of the case?
Thanks again for all of your help guys! I will try to make it to the range this weekend and see if there is any improvement after the gas ring fix. Should've been something I caught right away, but you know how it is, we often tend to overlook the simple things.
