So during this challenging time to find reloading supplies, i decided to tinker with the 223 vanguard 1-12 twist for a while. i loaded rounds with 50, 53, 55, and 60 grain v max all using 3031. The accuracy node with all bullets came in at the same powder charge with the 60 grainers producing the best groups. 5/8 inch at 120 yards. i thought this was interesting. just curious to here if others have found this to be true.
