Thread: "HELP" T3 with shocking grouping ???????

+1 for don't over tighten the action screws. 25 -30lbs torque max. If you over tighten you will compress the plastic stock and it wont recover. If you can get hold of another tikka stock from someone else try swapping that over to your action/barrel and torque actions screws carefully and < 30lbs.
If it shoots well you have your answer.
