Hello again,
I should have mentioned this is a K. Kale 1944, not the earlier cut receiver mausers. One of the reasons I was asking is just because the barrel is shot out. I have an over abundence of 30 06 brass and thought, "Since the barrel is shot out anyway, why not convert that old mauser to 25 06?" I didn't want to really change anything but the barrel.

I think you guys are giving me good finacial advice. I may just purchase a Remington 700 in 25 06 to play with and keep my Turk for parts for my brothers rifle. My brother has a converted Turk. His is an old Germanicon Mauser-complete with winter trigger guard and a small remnent of where they ground down and overstamped the receiver.
