is a m80 a quarter stick of dynamite
M-80 (explosive) Contrary to urban legend, an M-80 that contains 3,000Â mg of powder is not equivalent to a quarter-stick of dynamite. Dynamite generally contains a stable nitroglycerin based high explosive, whereas M-80s or any other kind of firecracker contains a low explosive powder, like flash powder or black powder.[6] Some illicits, however, contain(ed), or were reported[by whom?] to contain, small amounts of picric acid (similar to TNT), for greater effect.[citation needed]
Thompson submachine gun The Thompson was favored by soldiers, criminals, police, and civilians alike for its large .45 ACP cartridge, accuracy, and high volume of fully automatic fire. It has since gained popularity among civilian collectors for its historical significance. It has had, and continues to have, considerable significance in popular culture, especially in works about the U.S.'s Prohibition era and World War II, and hence is among the best-known firearms in recent history. Although the original fully automatic Thompsons are no longer produced, numerous semi-automatic civilian versions are still being manufactured by Auto Ordnance. These retain a similar appearance to the original models, but they have various modifications in order to comply with US firearm laws.
