bought a howa 308 last week ans it shot nice cloverleafs but since i upgraded the scope to a vx3 and put a suppressor on it it is stringing the shots verticaly in a 50mm line. I suspect i haven't done the action screws up correctly, they are tight but how tight should they be. Any suggestions, thanks.
o dear.... who was it that was playing with action screws @Gibo
Gibo has a screw loose, not sure if its only relating to rifles.
Did you change the rings too? If you are still using the shitty nikko ones they come with it is very possibly the threads on them are stripped as the aluminium is so soft, happened to my one, changed to weaver grand slams and problem solved.Quote:

My Tikka was doing the vertical string after I messed with the action screws. They just needed the correct torque and all was good.
Does it shoot well without the suppressor?
yes it was shooting 20mm groups, ill try it without the suppressorQuote:

Could it be a bad threading job? Bullet touching the suppressor ?
I think you might notice that quite quicklyQuote:

Probably should get a FAT wrench some day and check the torque on the action. Does anyone know what it is?
barrell is floating with suppressor on just fired groups with and without better groups with it on but still worse than when i first bought it. Action screws should be about 45 to 55 inch pounds according to the web. Ill get a tourque wrench tomorrow and see if this helps
Loosen them off then just barely snug them down finger tight and give the butt a couple of tapps on the floor pushing the barrel back into stock and snug up the front screw first making sure the barrel is centered then the rear.
It is not uncommon for things to settle after a few shots so recheck they are still firm after 5 or so shots and they shouldn't move again.
How clean is it? Could it be copper fouling build up?

Take the action out and make sure the bedding surfaces are clean a little piece of crap can really upset things. Then torque it back down.
i'm looking at a howa myself. cant decide between 7-08 or 308.
be interested to know which to go for
Thanks guys, i did the action down as vietnamcam suggested and tried it but still crap then had a brainwave and took the bipod off, which was on for the original good group, and three shots nearly touching. I wont be using the bipod anyway haha
You sure it's not your hold? I've heard an excessively light hold will generally cause vertical stringing. A tight hold with heavy cheek weld/ stock into sholder tending to spread laterally.
How fast did you get the shots off too? Is there a chance it was barrel temp?
let bit cool for a minute between shots, the suppressor heats up prettyquick. Probably was a combination of the way i was holding it and the bipod. All sweet now
process of elimination ......try without suppessor if still no good then thats not the culprit, check the recoil lug (if howas have one , i dont know) is fitted correct and the action screws are the right torque . im guessing the stock was removed to thread the barrel
