I recently bought a t3x in 308 used off the rack and it wouldn't approach 1" groups. Mostly 1-3/4" to 2-1/2". I am friends with the dealer and he let me return it. I know I could have worked on the gun to fix whatever was wrong with it, but I don't have the time to do that and who needs the headache. They should shoot out of the box much better. Having said that, I have not lost faith in the brand. I just receive the same gun in 7mm-08 and after the first round of testing have a couple sub-moa loads. With more testing I expect to have a selection of acceptable rounds to choose from.

You may not have the option to return it, so I would listen to the other campers with more Tikka experience and see what you can accomplish. It may iron itself out after you get the barrel thoroughly broke in.

I wish you luck. I know how frustrating it is. These damn guns are not cheap and it sucks to think you got a clunker.
