I swapped out the trigger spring for a lighter one for range use. It's just about 1 lb, which I thought might fire if bumped or the bolt closed too hard.
Well, since it's a composite stock with a Limbsaver mounted, I pounded it against a concrete floor. Nothing. I then tried slamming the bolt shut trying to induce it to fire. Nothing.
I'll say this, for the cheapest rifle Tikka/Sako makes it's got one hell of a good trigger. Light, crisp, zero creep.
I actually added a bit of weight to mine, in the form of lead shot in a vacuum sealed bag in the butt stock, packed in with foam padding. It improved the balance and reduced recoil a bit also.
I'd suggest spray foaming the stock to reduce that hollow sound in a hunting rifle, although I don't know if the foam may affect the Rubbermaid stock material.
