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

What Friwi said about the action screw torque. What have you been tightening the screws to? Just “tight” as in when the screws stop and a little bit more, or “proper tight” as is when the screws turn with slight crack noise? Did you use a torque wrench.

I have a few Tikkas and they all shoot brilliantly, except the one (308) after I overtightened the actions screws on and compressed the laminate stock. I was able to isolate the cause of accuracy loss quickly, because you can see the compression. When I say overtightened, I followed the instructions and used a torque wrench. Never really understood why the numbers are as high as they are, in the instructions, for soft stock materials. Anyway I fixed it by steel pillar bedding the stock and lifting the action ever so slightly, first with the coke can method, then by thin bedding compound. Problem solved, normal service resumed.
