Tikka 308win neck diameter

[HighUintas]

I'm looking for factory chamber neck diameters for Tikka 308win rifles.

I've got a factory barrel I was going to rechamber but not sure it will worth with what I want to do.

Can you guys who reload for this measure the neck OD on a couple of fired and unsized pieces of brass?
