If you could only take on gun with you into a situation that you know is probably going to be hostile, and you could only take one gun, what CALIBER would it be? We're going to say that cost is NOT a consideration.
I'm going with Deputy on this one...The only reason so many Americans don't like the 7.62x39 round is the somewhat confusing metric nomenclature. It's a good round, and you can carry a ton on stipper clips.
308 from short to long range out to a 1,000 yards I can hit it. I don't need a ton of ammo I need only the weapon I was trained with. If I get to load the ammo much more stopping power better bullet expantion also.
