5 rifles would cover everything I do pretty nicely, but I definitely have more. Here would be my line up, mix of function and class. I like nice walnut, and synthetic as well. This is from my current line up, and would give me plenty of overlap and cover all my bases for North America.

1. Cz452 22LR
2. Tikka T3x .223 rem
3. Tikka T3x 270 win (or 6.5 cm)
4. Kimber classic select 30-06
5. Legendary arms works Professional 300 win Mag.
