This is what 400LBS of reactive exploding target mix looks like when shot with a .223/5.56 AR-15. We put 400LBS of "tannerite" inside a RV and blew it to pieces. We thought putting it inside a RV would be a much greater show of how massive the tannerite blast really is instead of just exploding it by itself. The results were of Hollywood proportion. This is a NEW Youtube Record for largest tannerite explosion!! The most tannerite ever used!! Like and share our video and Facebook page, & share this video for a chance to win 1 of 10 SEG T-Shirts!
