I don't know about the 30-30 AW, but the 243, 6.5 Creedmoor, 270, and 7mm-08 that I've shot shoots great. I shot my RAR-Predator in 6.5 Creedmoor yesterday and the 129 grain AW was making sub-MOA groups, which made me very happy and very confident that any whitetails that gives me a clear shot is likely to go to the taxidermist and/or the meat locker.
The Hornady 140 grain Monoflex and 160 grain FTX 30-30 LeverEvolution ammo both shoot good groups in my Marlin and Savage rifles.
