Jo Jo;
Your poll passes up the best of the batch in my opinion. That would be a gun in 6.5 x 55mm Swedish Mauser. Outstanding accuracy, mild recoil, and kills all out of proportion to it's caliber due to excellent S/D and B/C numbers. I gave one to my then young son as his first centerfire rifle and he'd fight you like a wildcat if you tried to get it from him today.
There are several modern bolt action guns that have that as an available caliber, Tikka, CZ, and more. The CZ550 fullstock is one I've never heard a bad word about in either real life or online. Both the Tikka and CZ have well-earned reputations for accuracy also.
If I am limited to your poll however, it'd be the 6mm. My daughter took her antelope with one this year. It's a cartridge I'm thoroughly familiar with and like a very great deal. As the saying goes: The 6mm Remington is everything the .243 wants to be when it grows up.
Still, when game animals are included, the Swede is my first choice by a wide margin. I hunt elk with mine, sometimes out my back door, and don't feel under-gunned in the least.
