Bit disappointed that one of the all time great has been overlooked, anyway here my 2 bob

22 mag (economical, useful for animals up to meat goats size)
6.5 x 55 (wonderfully accurate, devastating with 155gr megas on all OZ game, Bovines excluded)
9.3 x 62 (can take anything, can be shot all day without developing flinchitis)
Marlin 30/30 (for when a quick action is needed, Boars)
470NE (sounds like a good idea)
