I saw a reference in this thread somewhere about 120-grain Partitions grouping less accurately than other bullets out of a Vanguard. Mine shoots them 3/4 in. consistently. It's my preferred hunting load for that rifle and has taken everything from coyotes, javelina and hogs to whitetail, pronghorn and mulies at distances from 20 yards to over 300. It shoots flat, hits hard and has never let me down.
The rifle is not a sub-MOA model, but obviously shoots MOA. My only modifications were an upgraded stock and a Timney trigger.
If you're fixin' to put a hole in something, make it a hole to remember.
