Thread: New Tikka .308 zeroing issues

Greetings JimmyJames and all,
Reading through some of the responces and looking at what could only generously called groups it strikes me that something serious is out of whack. The fact you managed some decent groups to start and things went downhill once the suppressor was screwed on shows something has changed. I would suggest two things. First take the barrelled action out of the stock and give everything a good eyeball. Especially look to see that the recoil lug is properly located in its recess. Give everything a good clean. Place the barrelled action back in the stock and do up the action screws finger tight. Give everything a good wiggle. Make sure that the action is not sitting on top of the recoil lug. Tighten the action screws but not over tight. Check your scope base and ring screws. With a clean barrel and no suppressor take it to the range with a decent target. See if you can get hold of a few of the NZDA 100 metre targets or something with a white round or square centre that you can quarter with the crosshairs. Fire one fouler and then three shots. Don't get up from the bench between shots and do everything the same. Do apply light downward pressure on top of the scope, every time. Just sit there like you were made of stone for the three shots. This will tell you if the rifle can hack it.
Second have a good look at the suppressor. If it is a DPT pull it apart and look carefully at the leading edge of the baffles for any strike marks. Make sure that the barrel threads are lubricated. Screw the suppressor on until it comes to a hard stop. If the threads are tight you may need to run it in and out a few times to ease things but the suppressor must be screwed on all the way. Repeat the range test with the suppressor on.
By now something should have become obvious as to the cause of the shite accuracy. You may just find the action screw or screws loose.
Regards and best of luck Grandpamac.
