I'm going to do this same thing with one of my stainless Tikkas in 270 or 30-06. I'm going to get a McGowen prefit barrel, maybe a Proof barrel, in 280 Ackley. I'm not with the group suggesting the McMillan; but, to each their own. There are a lot of companies now making pre-fit barrels for the Tikka action.
I didn't realize prefits would work on the Tikka action. I'll have to look into how they headspace.
