5.56.. availabily. the SHTF, and all governament, swat, police military will have ammo to use, trade for, or pillage
7.62x51... lethality at longer ranges
7.62x39... great for CQC, but not much else. also, not as available as 5.56


when it comes to getting shot i'm positive all of them are up to the task!

Now 5.45x39 is a dandy little cartridge that performs much better in the existing semi and auto platforms that it is common in. 7.62x51 has zero in common w/ either 5.56 or 7.62x39. 7.62x39 was original developed in the Soviet Union because of their experiance w/ the 7.62x25 in the burp gun. Instead of a sub gun, just send in waves of men w/ 7.62x39 and over run the enemy.
You are right about the 7.62x39. I have two SKS's that are super accurate. I probably went through a dozen of them to find those two. They just lack the knock down power to shoot a deer in the shoulder and put him down. Using quality soft point ammo I had to get a dog to find every deer I shot, even when the bullet went through both shoulder blades. If I had made the same shot with a larger caliber the deer would have been running on his chin.

you cannot discuss those rounds in their usefulness without discussing the firearms that utilize them. its just not possible to get a complete understanding without doing so.

traditionally the limiting factor of using a 308 for cqb has been the weight recoil and flash from using it in a shorter barrel. with the advent of things like the scar17 in a sbr config and utilizing a good shorty type supressor that ca handle the excess gasses its a doable round for that role.

the 7.62x39 isnt a good cqb round because there just isnt a good ak type gun that effectively eliminates or reduces its recoil and muzzle jump. while it can be suppressed great lengths must be jumped through to get a concentricly threaded barrel with the right threads to fit suppressors. the 7.62x39 was designed to fight a midrange conflict across the open fields and forests of europe and eastern russia. its a round thats time passed 30 years ago but remains popular because its a fun round chambered in a cheap fun gun. think mosin 91/30. even the russkies are phasing it out in favor of the 7.62x54r and 5.45.

the ar15 fulfills the cqb role excessivly well but it too falls flat on extended range engagements

the main reason no armies field a 308 is because its only really good for longer range dmr/sniping roles altho socom is using the scar17 in 308 which does all three cqb/midrange/longrange very well.

those rounds dont exist in a vaccuum
