I was going to email Tikka but it seems that they don't want to hear from the public as there is no email address for them. So I"m thinking about rebarrelling my Tikka which is in 300WM and want to know how much more can it take??? Any smith's out there know of any that are in bigger calibres then what's offered by Tikka???
Strength of a Tikka Action

My plan would be to change the stock and mag system so that's not a worry. Im more curious if it could handle pressures of a 300 Ultra Mag. Thinking about it now Im mother sure the action is even long enough for that caliber.
Why? Are the pressures of a ultra mag greater than a .223, 243, 308, 30-06, 300 win/weatherby/WSM etc? No they are all pretty much loaded to similar pressures. Your only problem is size and whether an ultra mag will fit in the tikka configuration.
Similar pressures yes, but does a .223 have the same energy as a 300 win mag? nope, and that definitely matters.
Chances are that only Tikka knows what their actions are rated for and its real failure point and fatigue life as bolt thrust goes up.

the 300 win mag is rated around 65,000ish psi ( Wikipedia has it at 64,000) .
I don't know of any factory rounds that are loaded higher than this .
what i'm getting at is , it you can make it function in the action , and it isn't rated more than a 300 win mag for pressure , you are good to go .
I would be hesitant with the recoil lug that they use - very weak design for big boomers, good for the lighter recoiling rifles - plus if you get a factory stock brace yourself for the recoil.
If the bolt head measurement is good, then all you'll have to do is put the proper bolt stop in.
Tikka email in Canada is under the Beretta/stoeger name. But don't know if they can help you.
Also, if you are buying the stock/trigger guard from Beretta, its crazy expensive. Stock and trigger guard with mag would be more than a complete new rifle.
There is a site for Tikka fans, Tikkashooters dot com that may have some answers for you.
I like tikkas, had 5 of them - but the aftermarket parts are hard to find and expensive - the T3's I had and tweaked cost me a pile o cash (new stock, stainless recoil lug, bedded the stock, metal trigger guard, bolt handle, aluminum shroud) for minimal gain in accuracy - was cheaper to go buy a 5r or add a couple hun and get a Cooper.
NONE of my Tikkas shot under two inches consistently except the 223. The rest were just average 2-3moa shooters, some which I was able to tweak to 1.5-2 moa shooters. I sent one back to Beretta for their MOA guarantee, but they said rifle was up to spec and sent it back, they do NOT hold that guarantee with handloads, told me that was my problem (yet Cooper only guarantees their 1/2moa accuracy with handloads...go figure!) and that fiasco took 6 months. After that episode out of principal I got rid of my Tikkas except the 223.
As I said I do/did like the Tikkas smooth action, the guns were relatively flawless, very reliable, well placed safety, great trigger, and their plastic mag is one of the best out there. They are a decent buy if you plan to keep as is.

+1 to that link. Do the math, if the bolt thrust is equal to or lesser than the existing chambering, you should be good to go. If the bolt thrust is greater.......err on the side of caution.
Also, I wouldn't recommend opening the bolt face at all to rechamber the rifle because that may (will) have a direct effect on lug strength
chrismc - just out of curiosity, were you ever able to achieve sub moa with any factory ammo?
When I first got my T3 Tactical, using cheap Federal hunting ammo it would easily group sub moa. I then started reloading for it with 165 SST and it was less than stellar and I couldn't even come close. Switched to 168 AMAX and right down to cloverleafs fairly easily. Lesson learned was that my gun HATED the SST lol
