.223 5.56 is expensive when compared to 7.62x39 so if $$ is a factor go with 7.62x39 if your just plinking/ zombie hunting.
You sure about that? Based on price comparison on SFRC website between MFS 7.62X39 & 223/5.56 ammo, 7.62x39 is more expensive than 223/5.56.
Some people on other forum said 223/5.56 is cheaper, but 7.62x39 is more powerful.
Anyone else?
