A YouTube user by the name of FullMag decided to test hockey pucks by shooting bullets at them. I don't know if this is an effective way of using one's time, but if someone has done something it's probably on YouTube.
Let me be very upfront in saying that I neither condone nor endorse this activity and that guns can be quite dangerous in the hands of an untrained professional. Please DO NOT recreate these activities in any way, shape, or form without the proper supervision and training!
Here's our Tennessee shooter testing hockey pucks against bullets.
That was pretty anti-climactic. According to the results, a hockey puck is strong enough to stop a .22-caliber bullet, but the rifle's larger-gauge blew the edge off the puck pretty easily. Again, we're talking about a one-inch piece of vulcanized rubber, so the fact that it can stop a bullet is pretty remarkable!
I would credit this as science, but there was nothing very scientific about it. For those who are in law enforcement or military, I'd stick with kevlar if you need bullet protection. Wearing hockey pucks would not only look odd, but it would probably be a lot heavier and cumbersome!
Until next time, keep your sticks on the ice!
