100 bucks says the metal plate is welded in place. You really should hinge them to fall backward, ergo the term, 'Falling Plate Shoot'. It absorbs half of the kinetic energy.
See the bullet hit the ground just in from of him to the left? Then it kicks up to clock him in the ear-muff.
Wow... he can thank his lucky star!
Got sidetracked and started watching some other silly stuff about guns on youtube with my boy and we clicked on a headline saying “why women shouldn’t fire a gun”. Too hard to resist so we clicked on a couple of videos, watched and laughed our a** off. You know now Google advertise on youtube at the bottom of your screen while you’re watching the video. Check what popped out while we were watching this chick firing an assault rifle. Weird hey?... not really
Difference in time from muzzle noise to metal plate noise is around 0.4sec. But, the bullet is moving at about twice the speed of sound, so 1/3rd there and 2/3rds back. 0.4/3 =0.133 sec from muzzle to target.
Muzzle velocity on a 50Cal is around 850m/sec, but speed tapers off rapidly, call it around 750m/sec average. 750 x 0.133 = 99.75m from muzzle to target. Safe to say that they’re on a 100m range.
I make it about 1.2sec from plate noise to ‘first graze’ (hits just in front of him). Sound travels around 330m/sec, so 1.2 + (100/330) = 1.5sec flight time of ricochet. Add another 20% for curved trajectory (must be quite flat) and that’s (100/1.5)+20% = 80m/sec (288kph), or 1/10th the muzzle velocity from the rifle or 20% to 25% of the Desert Eagle hand gun (also 50 Cal).
