Well Jeff there are quite a few 6.5s available, probably the 6.5x55 is the most common, just off hand x54, x57, x06, 264 win. mag come to mind. Something in a 6.5xwhateverR would be complementary to the gun. Availability of ammo. would be one of my prime considerations, nothing against wildcats mind you but I just can't be bothered. --- John303.
