I'm not sure what part of the world you are from, so you need could be different from mine.

From you list, here's the order in which I would rebuild:

.308 Win: General purpose medium rig.
22-250: Varmit rig
.338 Win Mag: Thumper
26 Nosler: Dedicated Long Range rig.

Everything else on your list is already covered with the above 4.

Then I'd probably add a good hunting handgun in .44 Mag and a good lever gun. If you want a .35, I'd make it a 35 Remington. An alternate would be a .338 federal in an AR platform, but that's the only reason I'd own a .338 Federal, especially when I already have a .308 and a .338 WM.

Those are just my preferences, guns selection is about what makes you happy.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.
