Don't know if Savage uses different chambering in different models or not. My Axis .223 heavy barrel just loves Sierra 69gn Matchkings (1:9twist). I am trying some 77gn SMK's and Hornady 75gn ELD match. First outing they showed some promise with a 2" group at 200yd. Trying some different charges of Varget this week to see if they will get down to the 1 or 1.5" range. Nosler 69gn match are also less than MOA.

I have not tried a lot of 55gn bullets. The cheap ones do not do well for me. If I am going to spend money for match bullets I may as well get the heavier ones as they do better at longer ranges for me.
