Accurizing a Grendel - Accuracy Advice

Do your groups pattern? Meaning are 2 or 3 close and then 2 or 3 close somewhere else, etc? I have had that happen more than once with Aero mounts. The zero would bounce around in a 1-2 MOA box. I don't use them anymore. The good news is that there's a very robust market for them on eBay.

Wish i had seen this earlier. I have a swfa 2.5-10x32 in an aero mount and was wondering why my groups are so big. Need to get that switched out and see if that helps.
