Still don't see the Tikka bolt issue. IIRC the last time I took the striker out the handle slipped in the dovetail rather easy.
I think there are still people out there that think you can solve a locked up action with a wooden mallet. A lot of Remingtons lost their handles to the same remedy. There is no reason on God's green earth to blow out the dove tail of a Tikka bolt. Unless you take a effing hammer to it.
