Has anyone ran TAC with the 75gr Amax in a 223 AI? How'd it do?
In my 22 1/2", 8 twist rifle using WW brass, CCI400's and sans moly I got the following:
25.5 = 2970 fps
26.0 = 3020 fps and stupid small groups, as in 0.4" or so at 100 yards.
26.5 = 3090 fps but groups were a bit larger and pressures had to be getting up.
With the 26.0 grain load, primer pockets lasted forever so I called it load complete. That load, in your rifle, may of course blow your ass up so be sure to work up!
