So while I was target shooting at connaught range with friends, as well as marking in the buttes, one of my friends had their elevation off, causing the bullet to land low, hitting the target frame, and ricocheting back into the buttes hitting a cement at chest height, about 6 inches from my friend.

I was wondering if anyone would know around how much energy the shot would have and if it wouldve been enough to kill my friend if it hit them in dead in the chest.

The bullet was an L42A1 military round (155 grains) travelling at about 340M/sec (it was still supersonic at 1000 yards) and the ricochet carved about 5-6mm deep and 4cm long gash in a cement wall.

oh and please tell me if this topic is in the wrong forum because this is my first thread.

In your first thread you should intorduce yoursrlf. I would suggest posting another thread with your introduction. Not a riccochet problem then we can go form there.

It sounds lik the bullet was still lethal to me,I know I would not want to get hit by it. I once had a friend that got grazed by a ricochet from shooting at at a concrete piling on a pipe crossing a river,it was a wake up call for him about shooting at hard objects with a firearm. And welcome to the forum.

We, just for the sake of supposing, if round was barely supersonic- 155 grs at 1100 fps is 416 ft lbs. Assuming it lost half its energy on the bounce, that would have be 208 ft ft lbs. And yes, that is definitely enough to be fatal.

Working from the other end- a 5-6mm gouge in concrete would equate to a bullet penetrating several inches into your skull. Minimum compressive strength of sidewalk grade concrete is about 3000 lbs/sq inch. Compressive strength of human skull a few hundred lbs/ sq inch.
