picked the 338 win. and considered the 30-06 mainly because you can find ammo for them most anyplace. you never know when travelling!
JH, you sure picked a winner with the 8x68s and its puzzling why most of the great continental cartridges, (7X64, 8X68s and 9.3X64)to mention only three, never gained popularity. none of these are new and all perform equal to and in some repects better than many of the much newer american 'magnum' rounds.
any one of them would certainly qualify for this list!
