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.
Why use a 50 pound bomb when a 500 pound bomb will do?
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.
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.....
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

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.
