I am still working up loads for mine. It like Hornady Match ammo with 88gr ELDM and 75gr ELDM but not the Varmint or Precision Hunter versions. I needed the brass so tried them all. The 88s were good enough for 1000 yards and showed how capable this cartridge is at long range. In handloads, the first bullet I tried was the Berger 85.5 HT that I already had on hand and used LeveRevolution, and IMR8208XR. All loads were OK but I want a load for 1000 yards. I need a "wow" load. My next steps are to try CFE223 and BLC2 with the Berger. I also have some Hornady 90gr ATip on the way and will be my next step along with some Alpha brass.
I really like this AR rifle. It is just so fun to shoot.
