I've only found one load for my abolt that will shoot sub moa, and I probably spent as much on different ammo as I did the rifle. Hornady light mags shot around 3/4", everything else shot 1 1/4" to 1 1/2". I dont have a tikka, but every report I hear about them says they are great shooters, just not that nice of a rifle IMO.

On second thought, I did shoot a 3/8" 4 shot group today with my savage muzzleloader, they are good shooters too. I still like my a-bolt better for actually hunting with it.
