Subject: [AR]Re: Explosion triggers
Tannerite a patented binary solid explosive isintended to be detonated by a
high velocity rifle bullet.Lesser velocitiesdon't work.The term you are looking
for is "brisance". The "sudden" of whatBen says.
Gen. Julian Hatch, NRA Technical Director for many years, has manyinteresting
thing described in his book, "Hatchers Notebook".In chapter 21,"Explosions and
Powder Fires" he discusses the requirement of "brisance" orshattering effect
required to initiate detonations.Later in that chapter(page 528) he describes
"Ignition of Powder by Rifle Bullets". They did sometests with soldiers
shooting Springfield.30-06 into 150 lbs cannister ofsmokeless power to see if
they could be ignited. Usually they would be. Butthey found if they shot the
barrel at the bottom with more than 2 ft of powerabove, the whole thing would
detonate. Knocked a sitting shooter 100 ftaway end over end he
said.Fascinating book, sort of an earlier incarnationof Myth Busters on gun
stuff.
