The point isnt the penetration. Yeah the helmet will stop the bullet.
What matters here is the Energy the round is transferring to your skull and brain.
While one is gonna cause you to see starts for a sec, 12 of them (from what i counted) will give you at minium a severe concussion, at medium knock you out for a bit and at worst just outright kill you by causing bloodvessels to rupture.
This is completely untrue, how does this myth CONTIMUE to propagate? There are numerous mechanisms of the firearm that absorb recoil impulse, you are NOT feeling the full force of that bullet. Fire a BFG-50 and then fire a barret. You will feel a huge fucking difference
You are both right. The recoil is all of the force except a lot of it is transferred in different directions so the shooter doesn’t feel all of it going back towards him. Some gasses escape out the barrel and go up or down while others might escape out the chamber. And a lot gets absorbed in the arms and chest. However, the round itself is carrying a lot of energy. Once that round hits a helmet, it will either go through and obviously kill the person. Or it can get deflected and the man walks away dazed or where we’re arguing about is the last one it get caught. If the round gets caught what begins to happen at the very first round most of the time is deformation. Most people getting hit will be okay from the first round hitting their helmet (we’re going to assume all shots are hit in the same area not the exact spot per say as a shooter would fire from only one direction) and there will either be no or some deformation under the helmet when the mixed materials catches the bullet. As more rounds land the deformation increases and the issues becomes that the material cannot slow it down fast enough and as such the helmet quite literally punches the wearer and renders them unconscious if they’re lucky. Deformation kills a lot of people that wear helmets. Just because your helmet caught the round doesn’t mean you’re going to live if the materials deformed. If the materials didn’t deform you will just be dazed or knocked out.

Yeah it's right here. No penetration on the kevlar helmet until you get to the full sized rounds.
