450 bushmaster prefit for tikka t3

[magtech]

I have a 308 T3 action laying around and i was curious if a 450 Bushmaster prefit would be plug and play with this bolt. I read somewhere that there could be brass-bolthead sizing issues. Just curious if anyone has played with this combo to see if its plug and play, or if id need to do some work to the bolthead.

I thought it would be plug and play with a .308 (.473) bolt face. Have read about numerous guys putting 450 tubes on Tikkas on snipershide and no mention of work to the bolt in order to make it so.
