Suit yourself, plenty of other left handed tikka options available.
To the OP, you’ll be well served by a stainless tikka for your use case. 30-06 is a great cartridge and will do everything you want, but so will other chamberings. If you want/feel like you need a 30 cal, I say go with 308 instead of the -06. If you actually do think you’ll do any longer range, an 8 twist 243 or a 6.5 creed is your answer. But honestly, any non-magnum cartridge in a standard stainless model is all the rifle you’ll ever need, no matter what or where you’re hunting.
