Barrel Measurements - Swedish v/s Turkish (K.KALE) Mauser

This information has been posted as a result of some discussion on one of the discussion boards. The question was raised - Can a Swede barrel simply be screwed on a Turk (K.KALE)?, What are the chances of achieving proper headspace? Note that the Swedish Mauser has only one torque shoulder, the front of the action, and the only (well almost) dimension that matters is the distance from that shoulder to the end of the headspace gauge. The 98 action has two torque shoulders, the front of the action, and the inner shoulder just ahead of the bolt face. By design, a barrel should bear against each shoulder equally when tightened. The Turks I have taken apart usually show signs of bearing only on one shoulder, but no shoulder seems to out number the other. It is easy to tell if the barrel on a 98k or M48 is tight against the front of the action, but harder on a K.KALE, because that area is hidden from view by the action extension. This table shows the dimensions of some of the "small ring" barrels I have encountered. Forster headspace gauges were used.

3	Swede-20"-new	0.625	0.120
4	Swede-20"-new	0.625	0.120
5	Turk-used	0.625	0.095
6	Turk-used	0.623	0.124
7	Turk-used	0.639	0.099
8	Turk-used	0.637	0.109

You can draw your own conclusions, I'll ad measurements as I can.
