Tikka problem

[Bobcat1926]

I have a new tikka 3tx in 22-250. Finally went to the range today to break in the barrel. Loaded round in chamber pulled trigger and firing pin dropped. Round did not fire. Ejected live round and not a mark on the primer. Manually decocked the bolt and the firing pin looked to be protruding ok.i think there rifles are test fired before they leave the factory but don,t know for sure.all I can think of is a headspace problem. I don,t have a gauge so I will shim the bolt face and see if the bolt will close on a round. I have two other tikkas and love them. Has anyone heard of something like this before?

I once had the same thing, the odd misfire. Turned out to be my front front tally scope mount screw protruding and catching the locking lug. I filed a hair off it and took care of the problem.

I was able to shine a light in and see the screw end in the locking lug recess. Might be worth looking at.

I think this can also happen if the bolt handle isn't fully down
