I was wondering, which has more penentrating power? I know that the 5.56 is 45mm in length and the 7.62 39mm in length, does that mean the 5.56 has more charge? Does a smaller round mean higher velocity? And also, addressing the realisms of some of the SWAT FP shooters that I play on my computer, which round penetrates Level 3 body armor? Or do they both? Which round is overall better in combat?
