Thanks WarPig, great video and sure shows that so often myths are touted when in reality physics is the truth. Sent this to a couple of people, one in particular who just doesn't understand what actually happens, expect he is going to be pretty upset with me but who cares. So often he spouts about what he believes happens and he is wrong.
It'd be more interesting if we (and the metallurgists here) had more info. There's steel, as in mild steel boiler plate….., and there's steel of course. And there's bullets - as in ball. And there's bullets as in AP. Interesting.
Lots of those you have to surmise...guess...
All a projectile is in a laymans view is a high speed drill somewhere I am remembering having read 60,000 revs a minute, and I am referring to rifle projectiles not those huge things fired from Arty
Just some info from what I remember When a 15" round hits the target say being A.P it produces a biscuit mili seconds before the round pushes through the armour this biscuit breaks free from the back of the armour plating and becomes a giant piece of shrapnel. And bounces around inside the area just prior to the projie detonating if it was a APHE. You can see this effect in the pistol bullet section as it breaks through the biscuit precedes the projie I have watched this vid allot prior and it is quite good. I believe it is not only about materials but also the angle of incidence.
As the Russians discovered in WWII the optimum angle is 60 degrees which give 4 times the thickness ratio so therefore 1" of armour sloped at 60 degrees = 4" of protection. Which was a nasty surprise to the Germans in the case of the T-34, hence Herr H- demanded a copy be made only better. So begat the Panther and as usual like the Tiger pressed into service before ready and suffered more losses from fires and break downs than enemy fire.....:confused:
If you want devastating impact check this one out, there is no way you would get up if hit with this thing with no B A on and that not breathing apparatus either enjoy

These videos make great discussion points during lessons. Especially when you can stop/freeze and group analyse points as they happen, reverse frame etc etc. Brings out the quiet pupils to become one of the 'wisdom of the crowd - or class' contributors. Had to watch it again to absorb some of the V interesting points

It looks like some of the clips are from a V50 type standard test for armor.
The target animals at the end are probably AR500 steel.
One thing here though, with the bullets(mostly) disintegrating on impact...people that don't understand any of this and take it at face value then get the impression that all bullets do that on all steel. I've heard it said by people that should know better...yet they will tell you there's no danger in shooting steel. Next thing you know, someone get's hit in the leg by a ricochet...(me), and then don't understand why I have such grief with close steel on todays range. Example, 454 Casull with lead bullets and 2 inch thick plate at 15 yds...38 spl with pockmarked steel at 30 yds...I can go on.
BAR you need to watch this one a very lucky Hombre.......
Guy hit in head with .50 caliber ricochet - YouTube
I couldn't make that link work...I'm guessing it's the guy in the gravel pit shooting steel? A railway rail...and it turned his bullet directly around taking his ear protection off? I had a bullet go through my hair over my forehead...that was close too...just one of many. Ricochets I mean...
A fellow showed up at the range with steel falling plates shaped like the upper torso and head. They were used in pistol combat matches and had taken on a cupped appearance from repeated use. He was firing .38 midrange ammo and one bullet bounced back and struck him on the zipper of his fly. It took three of us to roll him over to see if there was a hole or blood in his groin area. None was evident but we did take him to the hospital. They had to cut off his pants since the zipper no longer worked. He was bruised pretty bad. Those targets went to the scrap dealer. Steel is dangerous target material. I notice that most are cupped out rather than in to divert the bullet safely. I'll stick with paper.
