The 2 most consistently accurate bullets I've used in an AR, across a decent number of rifles, are the 69 & 77 gr SMK's..................when in doubt, always try one of those 1st.
If a rifle doesn't shoot one or both of those well (assuming 7-8 twist) then it likely will have bigger problems with anything else.
I still shoot a lot of 75 Hornady's because they are MUCH cheaper & accurate enough for most jobs, but never as accurate in the absolute sense as the SMK's.
Jury is still out on TMK's, IMO..............for me, comparable on smaller shot number groups, not quite as good as the number of shots / group increases in my trials & what I've also read in testing from other, in particular, MOLON over at AR15.com & on SH as he is basically an oracle.
But still more than good enough for most practical uses.............with improved BC over the SMK.
