exploding targets, not tannerite.

[Ala Dan]

A product called "ShockWave" is a dangerous, exploding target
with great impact that could cause serious bodily injury or possible death; if
too close to the target. Its white crystals come in a GLASS jar, that contains
a separate packet of mixture that must be MIXED and shaken up; then the lid
screwed back on tightly. Directions say, "Shooter MUST BE at least 100 yards
from target; and the target MUST BE shot with a least a 5.56 [.223 REM] rifle,
or larger center-fire caliber rifle. The danger comes from flying glass, as the
target explodes with a loud BOOM and lots of smoke~!

Yeah, the glass (one of the NASTIEST forms of shrapnel and BANNED under international mine laws BTW)

that would be a deal breakers, I find that plastic water bottles are great, they are SOFT and tend to burn and melt, I don't like glass.

See its hard to find, doesn't show up on X-ray (unless your lucky and got hit by LEADed glass-AKA Crystal) so your doc is stuck with the old way, follow the wound track and hope like hell

But nothing stops you if the price is right from mixing it and putting in a water bottle.
