On Sunday the 29th I was shooting at Bullet proof glass with a couple of friends of mine. This is the same glass that is used in Lenko Bearcats (the SWAT team vehicles) and brinks armored trucks. In addition, this is used in our vehicles overseas. The ammunition we shot was “off the shelf ammo” none of it was armor piercing. The following rounds went through the glass like it was butter: Smith and Wesson 500, Beowulf 50, 7.62×39 and 308 Win. The only calibers the glass stopped was 223 and Desert Eagle 50 AE. To finish the day off, we shot what was left with my Barrett 50 BMG just for the hell of it. Obviously it went right through it. All in all it was just a good day shooting.
