.22
.45ACP
.45LC

I obviously need a hunting rifle and defensive rifle caliber to fill the gaps
Hunting rifle choices;
.30-30, .30-06, .45LC
Defensive rifle choices
.45LC, .30-30, 5.56/223, 7.62x39
I like keeping my calibers to a minimum, fewer calibers to keep stocked up means I don't have to spread my ammo stock too thin, and it's easier to build up stock for the ones I do have
