If I had to pick 10 it would be:

22LR
22-250
6.5x55
7mm Rem Mag
9.3x62
375H&H
416 Rigby
410 Single Shot
20 Ga Double
12 Ga Pump

I could hunt anything on earth with that bunch.

But realistically all I need is
22LR
6.5x55
7mm Rem Mag
375H&H (or 9.3x62)
12 Ga pump


You get out of life what you are willing to accept. If you ain't happy, do something about it!
