why so many cal.s could't (.17 hmr fox and smaller)-(-22.250 up to deer)--(deer and boar???.270)--...(elk & bear size game.300win mag. ) ok replace .270 with what ever you have and i think that would do it?
22-250 is not legal in many states for deer and wouldn't be considered a deer caliber by many. Can't argue with your other suggestions. Variety is the spice in life and so you can never have too many guns, in my opinion.
