Sweet Jesus Man - you are a glutton for punishment aren't you?
Tikka, who's parent company I believe is Sako, is a very good, "lower" end of the production run Sako firearm. They will shoot, no question about that, but they lack some of the high end refinement of the Sako line.
The .338 is just a punishing, brutal round - so yes, you are going to feel it. The benefit is that if you get to Alaska, you won't have to worry about humping an artillery piece into the brush to stay safe.
For the price, it is a very good start on a completely effective hunting package. But damn, that sure is a lot of kick in such a light rifle. *winces*
