Home Forums Hunting & Shooting Hunter's Campfire Developing: Explosion heard in NYC, injuries reported. Sketchy------

High explosives having a threshold det velocity of 21k per second,tannerite, ammonium nitrate, dynamite,gelignite are still all low order (below 21kfps). I've used plenty of both and the high explosives act differently in effect. The addition of alumina boosts the heat levels of any blow to a very high level. A pressure cooker would hold about 10-12 lbs of TNT (HIGH explosive) and would have blown away half the front of the building and left a pretty decent crater in the concrete.
