One caliber/gun...for North America?

50 BMG, cause that’s the only thing you can get ammo for right now and I don’t see it getting any better.

Go big or go home?

7mmRM is the best all around cartridge IMO.

If I could only have one gun to survive it would be a 22mag. From rabbits and squirrels to moose.

One Gun??? Why?
I used to play golf with a guy who used a single adjustable iron - he would crank the loft down or up as needed. He wasn't very good.

I'm sure I already voted for 7mm-08, but just in case.
