Me, Stu, Dead2Sin n dan2sv650 turned a concrete cinder block into dust n one very scary large chunk got so much air off just one canister it took a good five minutes to locate it in the field of grass, needless to say we were glad I luckily canted it that direction without thinkin about it because it landed at about the same distance as the trucks were parked at 180°. The first time Me n Stu shot it I advised him to back up his new Taco cause what I'd seen on vids I thought might be able to change his door window into dust, but at 100yds you don't really feel much of the blast but you sure do hear it, reminds me of the morning cannon
