Hey there,
I have no experience with the Tika but, I do have an A-Bolt in 300WSM. It's been very accurate and reliable and is an absolute joy to carry. I put a Timmny trigger spring in the gun ($20 something) and now have a great trigger. If I were to start over, I would do exactly the same thing.
BTW, for me anyways I find the detatchable magazine to be a non-issue. I think that it is something to accidentaly lose...
Good luck. It sounds like they are BOTH good rifles.
