Both of my sons have Tikka T3 Stainless Laminates in .338WM. One rifle shoots about 1" with just about any load. The other rifle is newer and shoots about 3" groups at 100 yards. I have tried a number of loads in the problem rifle with no luck and today I swapped out the scope and mounts and fitted different mounts and a Nightforce scope to the rifle in the hope that it was a scope or mount problem. Unfortunately the rifle still does not shoot anywhere near as accurately as the other rifle.. Any ideas? The rifle seems solid in its laminate stock, trigger is good and the bore cleans up very easy.
