One other thing... If you're not dead set on the Tikka (should you not be able to get ahold of one), literally EVERY other rifle maker chambers ust about every CF rifle model they make in .25-06. You should not have any trouble finding a .25-06 that's to your liking.
Being LH his options are limited to Ruger who chamber 2506rem in southpaw versions of the Ruger Hawkeye.
You could see if your dealer could contacteither acanadian dealer or distrubitors for berretta (in canada)and broker a deal on your behalf, maybe an option??
