Front action screw a tad too long and bottoming out?
I had a new Remington Mohawk .308 where the screw protruded up and was jamming against the bolt lug.
Also a CZ457 where the front screw was too long and bottomed out in the action.

well lots of great advice maybe do a list of key points of here and go thru one by one - starting with the obvious - a magnifying glass would be handy - test for movement first -take action and barrel out and have a really good look - and as others have said that mount looks damn dodgy - but some great points on here to look for - even basics like does the barrel sit square in the stock or is it off to one side - the awnser could be bloody obvious its just one has missed it - this is a slightly weird one and I say that because its not a known problem with new tikkas - they are computor made and normally all come of the line shooting - but mistakes happen - saw a Remington a while ago and the bloody screw holes for scope mounts were out of line to action and barrel and a chinese .22 where the bore was of center to the barrel
