Sounds like I should swerve them. Ill give the 70 grn Bergers a try instead.
Try some 77 gr Sierra Match Kings. Based on "the rules", they should not shoot well in that twist, but they shot great in mine and others that I know of. Savage Mod 10 FP .223 24" barrel.
They even shot better than the 69 gr SMK which savage recommends.
The 75 A-MAX was okay, but nothing like the 77. I used 24.2 gr of Varget, prepped .223 brass (range brass if you can believe), Federal small rifle primers, .25 MOA every day.
