That certainly could work but not sure the twist would be ideal for that change?? Plus I'm pretty sure the 7MM-08's only come with the shorter 22" barrels.
What's wrong with a 22" .280? I'd just make it a .280 AI as it would probably clean up the 7-08 chamber. If it's a stainless .280 you want I'd look for a
Remington M700 Mountain Rifle.
If you want a Tikka in .280, just buy a .270 and pretend you got what you wanted!
