On it is a brand new Nikon Monarch so I find it hard to beleive it's the scope. And i have gone through and tightened bolts and mounts. The only thing i have left to try is check it for copper fouling, but it didn't shoot good groups when it was pretty new. Any suggestions on what to try/check for? I'm lost right now and have never even heard of a Tikka not shooting extremely accurately. And i have been using winchester factor 130s in case that matters. I am getting pretty frustrated with the gun. The only thing I've had happen while owning the gun was a broke an aluminum cleaing rod off inside it but carefully removed it with the other end of the rod and have been told that should in no way damage the barrel.
My t3 light .270 shoots incredible for about 5 rounds, after that the patter opens up from .5 inches to about 5 inches, then I have to clean the copper out and do it again. It is still a good rifle for hunting but it requires lots of upkeep, so I do not use it for plinking paper. Take some time cleaning it and get all of the copper out and then try it, make sure there is no more green or blue on the patches with a good copper solvent.
