Okay, got a new t3 some weeks ago. Factory rings are crap. Could be be made better for a nickel but apparently tikka choses not to. Tried the factory rings tho and couldn't get it to group. Checked everything for tight, new Weaver bases and rings, several types of ammo, still minute of 5 gallon pail groups. It's a .243 so I have tried to find the weight and type of bullet they test with at the factory but apparently it's the Finnish national secret. I don't reload so I just want to buy a box of ammo and snipe at the vermin behind the house. I know there are guys who love to own rifles that will only shoot rounds that have been hand loaded by the Pope, kissed by Selma Hayek and polished with pixie dust, but not me. I have a CZ and several Savages that will group anything I run through'em but I wanted a .243 so I went off the reservation and bought a Tikka. So far it's a POS. I'd love to know the factory rounds if anyone knows.
