text: In reply to message48129: The Grammar Nazi striking again (sorry). But, that is NOT spalling. Yes, almost everyone uses that term, but what you are showing is "splatter". "Spalling" is actually the BACK of the armor 'shooting' a small piece of itself off. Think of a plate glass or armored glass window that has been struck with a BB, the cone shape on the back of the window is "spalling". What is being demonstrated in this video is "splatter", the fragmentation of the bullet into smaller and smaller fragments. Yes, I know, almost all of the videos (esp UTube) call it spall, but if you contact them, they will agree that it is 'splatter', but they use the term spalling because that is what everyone else does. 'Splatter' stays in front of the armor, 'spall' goes out the rear.
