This article says a 1:14 is good for up to 55 grain bullets but other articles say 1:14 is good for "only the lightest bullets" [ie 40-45 grain].

I have a M-70 .223 carbine, 14" twist. It has trouble stabilizing 55 gr in the 19 3/4" barrel. The AI has enough more velocity that it may
even stabilize 60 gr but I wouldn't bet on it.
