Hello all, I have read various posts about trigger adjustment on the Tikka T3. I invested in a Lyman trigger pull gauge (~£40 off Ebay) and set about the adjustment. The manual clearly states not to adjust below 2lb. My T3 was breaking at just over 3.5 lbs, as originally bought new. I removed the action, put the rifle on the gun maintenance stand and carefully adjusted the self locking cap head to give an average consistent break of just over 2lb. A simple and easy task for anyone to do.
After re-assembly with the rifle empty I did the recommended 'bump' tests on the stock and then with a rubber pad under the barrel. I also cycled the bolt 'excessively'. All was fine.
I went off to check zero and get a feel for the new trigger pull. In summary I am delighted, a nice cleaner pull and tighter groups. Since then I have taken the rifle out on the bucks with good success. I would recommend to any T3 owner to adjust if unhappy. The trigger pull gauge has already seen other use and is useful to have.
