Trying to get ready in case I can go to Talladega for the EIC match in June. Was wondering if some people were still on 69 grain or stepping it up to 77 grain or 80 grainers? I will be using either Varget or RL-15. Somehow I'll have to figure out if I put 1/4 min. or 1/2 min. rear sight on my AR, I forgot which one I bought.
