Had a Tikka 243 new. Could not get it too group at all. Tried every thing ,strip,clean ,back too shop,mod-on,mod-off, back to shop, back too range diff ammo ,back too shop,bi-pod, sand bags ...........ball-bags too this I thought, back too shop. In the end it became heated with the supplier as they now blamed me a walk through the garden off understanding we comprimised and too cut too the quiuck I now have a Howa .
I have since heard that the 243 for this make is a problem round for whatever reason. Down the club a number off members have heard off grouping problems with the Tikka/Sako
