I have a load using the 75 grain Hornady HPBT bullet using IMR 4064 powder and CCI BR4 primers. However, IMR 4064 is both rare and expensive. Accurate brand powders are more available, but I have no experience with them. What AA# powders are intended or known to work well with 69 - 77 grain bullets? I'm also looking into Shooters World powders and use AR Plus and Tactical Rifle in both 308 Winchester and 223/5.56. For what it's worth, I very rarely load bullets to full 5.56 pressures.
 
Not that cheap but Accurate 2495 would be worth a try. The 2520 ball will likely meter better than the 2495 stick powder.
 
I have used A2460 with a 69gr Barnes Match Burner and a 69gr SMK but the 1:9 twist of my rifle will not stabilize heavier bullets. Other alternatives could be TAC, I still use a lot of that. Also BL-2(C) works well with heavies, both are readily available and inexpensive.
 
TAC.

The bonus with TAC is it is a fair substitute across the board for IMR4064... 62grn and up for the 5.56mm, and it works really well in .308, primarily with 165/168's, but reasonably well with ~150's, too. I've not tried it with 175's yet, but it's on the To Do list. It works well in semiautos, too. I've even got a load worked up with it for the Garand...

My gun loves AA2520 with 69gr RMR.
 
Looking over the Hornady data, it seems like AA#2495 and AA#2520 are the ones to try. AA#2230 seems like it's a bit too fast.
 
AA2495 was designed to ballistically duplicate the 4895 powders. Why they didn't name it 4895 is a question for someone else.

AA2520 was supposed to be a ball powder pressure-curve duplicate of 2495/4895. How close it comes to that I wouldn't know.

Maybe that will help with your decision.
 
Accurate makes a 4064 that is also extruded. I went with n135 when those were the only two choices on the shelf. If you like ball 2520 is sooposed to be very good but again like Charlie98 said, when given the choice I went with tac. Tac/2520/n135/imr4895 all seem close. N140/imr4064 and maybe AA4064 are slower. I haven't used the accurate 4064 but I wouldn't be afraid to.
