Indeed Azeem, the 762 Russian round is effective in its own right. And I know some folks swear that their AK variant will hit a gnats eye at 600m. but we know better.
As this youngster ( where the F was his battle buddy/daddy?) learned, you can not have too many rounds at hand....

Right now 7.62x39 can be purchased for .30-.32 cpr. 5.56mm and 9mm are going for double, at least.
If I’m going out to 600m+, the 7.62x54R and .308/7.62x51 are preferable.
