All my 30-06s shoot well. The Handi's shoot best. My two Handi's shoot better than I am capable of shooting most of the time. Now as for bullets, it depends on what I am going after. My rifles handle all weights from 125gr to 200gr about the same. Now that said I have three favorite bullets. For animals under 100lbs I like the Speer 125gr TNT. For Wolves, Black Bear, and Caribou, I like the Sierria 165gr Speer Point Boat Tail. For Moose and Grizzly, I like the Nosler Partition 180gr. The problem with the 200gr bullet is the range just is not there.
This year I have loaded some Nosler Accubonds in 165gr, in front of Reloader-22. On paper I really like the load. It's flat shooting enough, that without changing my scope from the 165 Sierrias in front of 760 (factory duplication load sighted for 300 yards) I am dead on at 400 yards. I'm shooting a 2 3/4 inch group at 400 yards off a rest. Have not shot animals with this load yet, but taking it with me to Texas, Tennessee, and Florida later this month. Maybe I will get some Whitetail and Hogs.
