Try Century Arms as well as Samco. Always a goodie, I used to trade alot with them back in my FFL days.
You have a lot of good rifles in mind - I have always fancied the Enfield myself, although I havent seen any rechambered to .308 for sale. And if they were, I believe that would void the C&R status ~ AFAIK.
So, allow me to offer my single recommendation for a bolt rifle:
Swede Gustav Mauser in 6.5x55 MM. This bad-boy should be at the top of your list. Almost no pushback in the milsurp guns, little bark, the ammo has gotten downright plentiful these days and lo and behold, they make a bunch of modern rifles in this fine old caliber. You can't say that about the .303 Brit, 7.5 Swiss, 7.62x54R or even the venerable 8MM Mauser round, AFAIK
While any of the mentioned calibers (and more milsurp stuff) will take deer sized game, the 6.5 does so without blasting you out of your tree stand, AND any bona-fide hunting arm would also share the caliber with your C&R Mauser. Now that's value, brother!
CAUTION: I recently learned a bit about milsurp vs. commercial ammo. Let's see if I can summarize:
Due to variations in headspacing, powder and primer combinations and other factors affecting the interchangeablity of ammo and rifles on the battle field - milsurp ammo is generally loaded to lower pressures than commercial ammo. It is NOT recommended that you shoot commercial stuff in your surplus rifles. Handloads intended for surplus rifles should also be held to lower pressures.
As far as collectible old bolties go, the Swede I have is a piece of forgotten craftsmanship and is worthy of being taken out of the cabinet from time to time, just to admire. They really dont make them like that anymore.
Oh, and dont forget to add an SKS to your list. And one of the Nazi P-38's, a Czech CZ-52, one of the .32 PPK knockoffs, something in 9x18 Mak, a Nagant revolver......
