semi - 6ARC
bolt - 6 Dasher because you can push a high BC bullet out to 1200 no problem and it will be accurate from 100 to well over a half mile, very little recoil so spotting misses is way easier.
Pistol - 10 mm
Tikka over the ruger
I'm not sure what you will do with it, but another option is the tikka CTR for under 1000 put it in a KRG Bravo, now you will be able to change the scope rail for a 20 moa rail, I'm pretty sure the Tac A1 has a fixed rail so you'd have to use canted rings to go out further...
