Sir:
I understnd - I get sick of certain calibers too, or, just want a change.
By the way, that Rem. 798 is the old Mark 10 Mauser action made in cz. They were sold by several companies and are good actions! However, I really like the lo-swing safeties rather than the action mounted triggers, and safeties - I even like a smooth military trogger!
The 308 is a great cartridge, I've got a "target" chamber reamer for it and have made a few in my time.
It suprises me Remington went to that action - it shows that the 98 Mauser was and is the best action on earth.
The 700, after you tear one down doesn't have the inherent strength of the Mauser. That "three ring of steel" is a crock - if a case head expands and goes you've got a junk action - with the 98 it just might vent out and not damage the action ring.
The Turk 38 Mauser is a good one - I've built 9.3X62 and 9.3X64 and 416 Taylors on them - good actions, hard where they need to be!
I wish you happiness with your choice - hope I did not offend you.
