There is a lot of debate as to the which is the better survival cartridge. These two cartridges are mentioned more than anyother in a apples ot apples comparision but really is is apples ot oranges. Simply it is the 5.56 has greater effective range is flater shooting and has faster ballistics...
The two primary cartridges for survival defense are a carbine cartridge and a light rifle cartridge. For defensive purposes most of us will consider one or both fo the following.
The 7.62x39. http://en.wikipedia.org/wiki/7.62x39
