Energy vs how it feels

Ok so we all see the charts with ft lbs of energy. Lunch time debate at work. We are installing ballistic sheathing on a job. We shot several pieces with a 9mm and a 45 long. We could not recover either bullet. They were swallowed up or disintegrated with hardly a mark. If you were on the back side holding it how would it feel. Does 400ft lbs of energy feel like 400lbs. I doubted it but yet am drawing a blank as it logically makes sense. Anybody know?

Re: Energy vs how it feels

I believe it would depend on the surface area of the piece you are holding as well as the distance of the muzzle to the piece. a ft•lb of energy is the force of one pound displaced over one square foot. A larger piece held at a longer distance would feel like much less force than a small piece at close distance due to the projectile slowing over distance and the impact energy being spread out over a larger surface. Just a total educated guess though, I wouldn't be the one holding to find out!!

Re: Energy vs how it feels

No it does not feel much more than what you felt when you fired it. Equal/opposite reaction.
The "energy" is confined to a very small area about the size of whatever bullet being used. Look up 2nd Chance Armor on youtube. The owner has body armor on and gets shot point blank by a .44mag. Then stands on one foot while getting shot point blank by a .308 Win. He does not even even lose his balance.
Energy allows a bullet to do what it is designed to do but bowling people or animals off their feet is not one of them.

Our forefathers didn't bury their guns. They buried those that tried to take them.

Re: Energy vs how it feels

Energy from a fired round feels like a push or a shove when your standing behind a ballistic shield. I can tell you getting shot feels like a lot like getting punched.

If you want to test penetration on your ballistic shielding you need to use the correct bullet at the right velocity.

Re: Energy vs how it feels

I was shot in the chest with a Winchester 32 Special when I was 18 from a distance of about 50 feet..It felt like a giant boot hitting me and it knocked the wind right out of me and spun me around, but I didnt' fall down...I just stood there in complete bewilderment until I started to bleed out of my mouth...Then shock set in...The guy who shot me actually looked worse than me!....Anyway, long story short, they got me to Shamokin hospital where they cut me open right across my right pectoralis major and removed part of my right lung.....Bullet jacket was found in my clothing and the rest of the slug stopped just under the skin in my back...Two weeks in the hospital and in a month I was back out hunting !
