In short, the slower twist barrels with the old 55 grain fmj 5.56mm slug made much more damaging wounds out to its max range of =-400 yards from an unscoped M-16.

The fast twist barrel shooting the new 62 grain AP rounds is more accurate, out to +-600 yards, and penetrates very well against helmets and vests, but tends to make a neat "knitting needle" wound which is not an instant man stopper as they discovered in Somalia.

However, in civilian use, a hot .223 HOLLOWPOINT is going to just tear a person up, as we have seen with 7 out of 10 dead.

Yep.

Can you explain real quick the difference between a .22 and a .223. The size of the round is similar, but what differentiates them?
