Toney if you are going for a 7 Mag then just be sure to get a Tikka with a mag bolt face. Or you can just have a non-magnum bolt face opended up but thats more work than if you just found a good deal on a 300 WM or 7 Mag.
Also you can simply have your Tikka T3 Lite barrel threaded 1/2X28 and then bushing up from there to whatever you want. I have had 3 tikka lites threaded this way and bushing up to 5/8X24 so it'll work with a suppressor.
You can see the bushing under the thread protector there. Disregard the poor mans full arca rail that extends like a spigot.
