If you had to choose 3....

[bustedoldman]

I'm still in the process of reducing my collection down to one safe.......So if you could have only 3 bolt action rifle calibers (.24 or larger) what would they be and why? Also feel free to suggest a manufacturer/brand/model etc etc.

[wadu1]

To keep it reasonable, personally I would look at this group. One in 6-7MM range, one 30 of some sorts and a large bore 35+.

[blackpowderhunter]

many will probably disagree with my love of the .300 wby..
but, for 3 rifles of .240 or larger...
a 6.5 creedmoor or prc for a "small bore", 7MM-08 for a "lighter" load mid range type gun, and a 300 wby or 300 win mag. for heavier bullets/longer ranges
i don't see why you'd "need" anything bigger than a .30 caliber but that's just me using logic and reasoning, and when talking about guns lets throw logic and reasoning out the window 
love my weatherby accumark for a factory rifle...

Calibers:  6.5, .30 and .338

Chamberings would be:  6.5 creed or prc, 300wsm, 338 lapua. 

This is specific to bolt rifles.  I also need a few lever guns in my safe.  45/70 or .450 marlin

If only 3, and I'm thinking sporting, hunting and the post-apocalypse world, two would be NATO cartridges, .223/556, 308/7.62x51, and the third would probably be another medium bore...Likely a 6.5CM or 7-08.
They would have fast twist rates and detachable mags.

These were similar to my thoughts as well....Yes just downsizing to 3 " Hunting/LR" bolt guns, there will still be 5 lever guns in there and varmint cal bolt guns also.

.243, .30-06, .50 BMG. If you'd accept a lever action, then switch out the BMG for a .45-70.

.300 WSM

.300 win Mag

.303 British

[Pathfinder101]

6.5 CM (go ahead... flame me... )

I know that is 4,  but hey, one extra is a bonus!!

[highside74]

223. For varmint hunting
7mm-08 or 6.5 for deer/bear
7mm or 300 for elk/moose

[wheels1]

7 saum or wsm  300wm  maybe 375  if you ever want to go for something really big

[GASoline71]
