Wow- might have to change the old Military satchel charge based expression of "Fire in the hole" to "Fire in the whole" da whole Eastern sector of Kansas- Mama Mia that's some hefty load- what F grade Black Powder- pyrodex? A cannister charge perhaps? Sorta makes me think about a John Belushi WW11 spoof movie- where the CO says "Let's go out and blow up something really big"!--
