YOu can 't buy accuracy
But you can buy inaccuracy.
Its 20 degreee below zero and your polycarbonate bolt shroud cracks on your Tikka what do you do next ?
Call 'Ripleys Believe It or Not' because it's never been 20 below in the recorded history of my state. And any deer out roaming around in 20 below weather are safe from me.
Spend the extra couple of hundred and buy a real gun Sako 75..at least no plastic except stock and dead reliable gun.
Sako makes Tikka's. Like the plastic on the Tikka or don't like it but one gun is just as reliable as the other. If you plan to run your game down on foot and beat them to death with the buttstock of your rifle, or you plan to use the magazine clip from it to crack walnuts on an anvil then by all means stick to an all metal configuration. For the vast majority of us that plan to simply "SHOOT" our rifles you will have no problems with a Tikka and it's few plastic components. In fact in my 39 years of life through some pretty hard hunting I have never done more than scratch the barrel or wood finish on a gun. I guess some of you guys must be hunting from hang gliders or something.
