I have been looking for the hornady 75 gr bullets for some time, they are sold out everywhere.You'll need a 1:9 or faster barrel to shoot 77s.
I shoot 77gr CCs in a 1:8 18" AR15 with 23.5gr 8208XBR (book max is 23.2gr) and had great results in two different 1:9 Savages using the Hornady 75gr HPBT and 24.0gr Varget.
