23.8-24gr of tac. It puts you in 556 pressure, my 16" is hitting right at 2700fps with single digit sd.

24 gr tac gets me 2740 from a 16 inch and 2420 from an 11.5 inch.

It looks like a load in the neighborhood of 24.0 grains (Johnny got the best accuracy @ 23.9 & 24.2) is spot on for an accuracy load.
I run 24.5 of Tac with the 77 SMK and CC. This round is hovers right around 1moa at 100 and makes hits at 600 easy with my 13.9 Criterion.
I also like that I don't have to change my powder charge at all when going from 77 grain to 55 as my blasting ammo is also 24.5 grains.
Add me to the group that is getting lower than average speeds with TAC.
24.0 = 2549 avg SD 9 ES 18 with 77gr SMK
24.3 only got one shot across the chrono that read 2650.
Im not mad as I have H335 in abundance and have a good load for it making 2700 out of my 16".
