Accuracy was still acceptable but marginal for what a 223 is capable of, but was not a clean round hole like the 55 gn did. I tried 69 grain Sierra HPBT Matchkings in it just to see where the upper limit was. It shoots 55 grain Sierra HP Gamekings just fine. I have a Win 70 223 rechambered from a 1:14 twist 222. If you are only planning on using 40-55 grain offerings 1:12 or 1:9 are not an issue.
