What velocity are you getting from a 16" AR with 75 or 77 grain bullets?
I'm curious what type of powder and velocity.
I have settled on IMR4064 with a 77 SMK and am averaging 2655 with an ES of 14.
 
I have a load with 75 Hornady BTHP over Ramshot Tac and #41 primers that gives just about 2725 in my Criterion 16" Wylde chambered barrel, about 100fps less in my wife's NATO chambered Sig 556. It's very accurate in both. It's a little temperature sensitive, being a ball powder, but not terrible, and meters incredibly well, so i can bulk load easily on a Dillon RL650.

That's pretty fast. I've heard good things about tac.
