Rito. . .. a friend has a barrel threaded for a Sako 85 and I'd like to screw it into either a Sako 75 or a tikka T3.
From what I've read there seems to be a lot of debate as to if the threads are metric or imperial and if or when they changed from imperial to metric or vice versa in the earlier and later models. Some say that the threads are actually metric 1.6mm pitch but it's close enough to 16tpi that they just force it on anyway.
I'd like to know what the ACTUAL thread pitch of the actions are and if the 75, 85 and T3 are interchangeable in both thread pitch, diameter and head space (good enough for a wildcat 6 dasher).
