We call it the big brown box, because that is what it is. Eight pounds of trinary fun, in one big box. This is a slower mixture (for safety's sake), but will still rattle your cage pretty hard, and make one HUGE signature. Our minimum safe distance is still 100y/m, but we use these for our 1000y targets with good reason, they are big, bad, noisy, and mad!! Explosive equivalent of 12 pounds of common binary.
