I don't think 5.7 (non military version of the round) is good for civillian self-defense....
Consider the following...
Civillian encounters with bad guys most often occur within one car length (bad guys have to get that close to take what you have). So we are talking about short range in the vast majority of cases.
The way a person is "stopped" (as opposed to killed 10 minutes after being shot) is by bleeding out in a hurry...sudden loss of blood pressure. Big holes center mass is better than small holes....which is why hollowpoints are so popular...
At close range, a 5.7 with max energy would most likely punch straight through the target, leaving a very small hole. I'm not even sure if the double cavity wound that high powered rounds usually cause would even be formed, unless the "military" deforming version of the 5.7 ammo is used...
Has anybody tested the "civillian" version of the round at very short range on ballistics gel?
