Like Jackwire says exercise some patience with your rife.......you have only tried one ammo. I have a 30-06 spr. In a Tikka t3 stainless lite. I have shot about 3 boxes of Hornady 150 gr. American Whitetail and from a rest at 100 yds it groups them approx 1 1/4" at 100 yds. .......sometimes a cloverleaf......sometimes close to 2". It shoots Remington Core Lokts and federal fusion about the same (all lower priced ammo). I have not tried high end ammo in it yet because it is a meat gun. It thumps pretty good because its light, but its a joy to carry.
p.s. i have 2 Remington m700 stainless in .308win and they both shoot core lokts to 1 " and i have had great success with them.
