John, I could find no data for the .223AI and TAC so I extrapolated from regular .223 data. whistle

My precise calculations put 29.0 grains as the top end....my load of 28.5 showed no signs of pressure whatsoever...


I'm gonna take it out and run some through gun#2 to see if the results are the same....
