Hmmmm....

A .22 rifle and pistol for all that 22 LR ammo I've stashed in anticipation of these crazy times and ammo scarcity.
A 12 gauge shotgun for turkeys, a 20 gauge for pheasants and quail. Maybe a .410 for a challenge hunting turkeys.
223 for varmints.
A 243 & 270 for deer and bear.
338 for elk moose and bigger bear.
A 45-70 for bigger bears.
I had thought about a 9.3x62 for bigger game in the states but am considering a 375 Ruger for the same thing.
