If you had to have only three?

Since I don't hunt varmints my choices would be:

6,5x55SE for normal hunting up to 600y, 9,3x62 for driven hunts and stalking, .338 Norma Mag for ELR...
 
22-250. Inexpensive to reload. Great for training.
308. Infinite combinations to experiment with. Long barrel life.
7mm Rem Mag. Because that's my Sako TRGS and I'm never giving it up!
 
Ones I have: .243, 7mm RM, 338 Norma

If I did it over: 22-250, 280 AI, 300 Norma Magnum AI
 
Well my current 3 are:
6mm creedmoor (competition)
6.5 creedmoor (whitetail, black bear)
7mm rem mag (universal lr hunting/target rifle)

What I would like my 3 to be :
6mm creedmoor
6.5 prc or 6.5 saum
7mm rem mag
