I bought a T3 30-06 S/B last summer. The ammo I tried prior to the hunting season was:

Federal 165 grain Sierra Game King
Federal 165 grain High Energy Trophy Bonded Bear Claw
Remington 180 grain Core Lokt
Remington 150 grain Core-Lokt
Hornady 165 grain BTSP

I had the most consistent performance from the Hornady ammo. That said, I went with a heavier bullet as I was trying to find something that I could use for whitetailed deer, Moose and Caribou.

Good luck,
