Tikka t3

Does anyone know if the standard calibre tikka t3 (.243 .270 etc) uses the same bolt face as the magnum calibres (7mm rm 300win mag ) ?
 
No, it cannot. The 7mm Rem Mag and .300 Win Mag, like the .300 H&H, are based off the .375 H&H.

For example, in something like the swappable, modular, SIG SHR970, made for them by JP Sauer, to change from .30-06 to .300 WM, you must change the barrel, bolt and magazine.

Thanks for the replies I don't suppose any of you know if the bolt face could be opened up to take magnum a cartridge with the t3 action being one size in other words convert the .308 to a 300win mag ? Or would I need a different bolt
 
I was under the impression that if there was something you were not certain about it was better to ask my mistake

Hi Benji

From what I've researched it is definitely possible to open the boltface out sufficiently. It is the extractor that is the problem. The extractor slot needs to be welded up and remachined to bring the extractor out to suit the larger case. Maybe it's possible to get a special extractor made instead? I think it will prove to be more cost than it's worth.

I think that you'd be better off selling your rifle and buying a suitable donor.
