It’s a lightweight barrel without threads. I could buy an adapter or change the barrel but the action on my current rifle is junk. Struggles to cycle with anyone who has shot it
Yeah, I've never seen the point of throwing good money into a mediocre system.
As for other comments on this thread.
A stock Tikka works perfectly fine. The reason to upgrade is based on preference. Anyone who say you "need" to upgrade a Tikka is not very objective (though like in that Cliff Gray video I say that as my Tikkas have been improved on). You have the option to upgrade Tikkas, you have significantly fewer options option on X-bolts. That may change with time.
If you like a stock X-bolt, then get one.
The 6.8 Western is another post 2000 Winchester cartridge that will likely slowly die. Nor is it a cartridge for high volume training. It is the recommendation that ignores 90% of your OP.
I personally really like short barrels, and this X-bolt looks like a nice configuration and comes threaded. Fluted bolt is a negative to me (lets more junk in the action).
This Tikka comes threaded. Barrel is a touch longer than I like.
Or this one gets you Cerakote (possibly over stainless) though I'm not a fan of fluted bolts.
This Sako would be my choice if I wanted an out of the box rifle with no intention to modify. Sako's take Tikka barrels. Their cost is not objectively justified when compared to a base model Tikka.

If you can spend Sako money, I would say getting two Tikkas, a 223 trainer and a 6.5 creed, would be more valuable. It is slightly a pain, but using a pic rail you can swap a scope from one rifle to another pretty easily.

Sell both your other two rifles to justify it.
