    The cloud of smoke looked to me like, what I would picture 3 or 4 pounds of Pyrodex or similar going off at once. Am I way off base? Or if I am way out line with this thread,Mods delete it

    You're not the only one to think that. :(

    The question is, would that size pipe bomb have resulted in the traumatic amputations we saw? I was surprised by the damage of the blast, after looking at the video of the blasts themselves.

    Of course, my experience with IEDs is pretty nonexistent.

    Big boom, white smoke...it is to worry.

    The damage I saw I would THINK would require more boom than is in traditional propellants, but I could be wrong. Any explosive experts around here?

    my thoughts were... "wonder how they'll blame guns for this?". Then it hit me, this will be the tragedy they need to start restricting reloading components.

    I'm far from an explosives expert, but I was thinking black powder or a substitute as well. I'm not sure that a pipe bomb would cause that kind of damage though. Black powder should explode only to the point that the container fractures, meaning that unless the container was designed to fracture like a grenade, there shouldn't have been too much shrapnel caused by the bomb itself.

    You don't need to buy black powder to do that, if you have the time black powder isn't that difficult to make. Then again, when was the last time logic stood in the way of someone passing a law?

    Edit: A chem-engineering friend was thinking ANFO considering that it makes a rather dirty explosion as well.

    What is ANFO ?

    ANFO is short for Ammonium Nitrate Fuel Oil. It's what people mean when they say "just mix fertilizer and diesel fuel". Pro/con from an explosives standpoint is that it is a very stable mixture, but is a bit difficult to detonate when compared to other things you can use.

    Google is your friend ;) Link

    News reporting that Dr's were digging ball-bearings out of the victims.
    These jerks were aiming to maim & kill.
    Could well be black powder; witnesses report smelling sulfur

    My first thought was black powder, and everything I saw in videos and pictures confirms some sort of low-yield explosive.

    I think even ANFO would have more oomph and less smoke than what the videos show. There were windows only feet from the blast that were intact, and victims who had been engulfed in the fireball (burnt hair and smoking wounds) who were still conscious and apparently not significantly affected by blast/concussion/overpressure.

    Just be thankful that the bombs were placed right on the ground and that not all of them went off. If the guy had known what he was doing, it would have been worse.

    Well we know most criminals aren't smart enough to make their own blackpowder like some of us including myself do. And we know that in NY you need a permit to buy ammo and probably BP too.

    Could it be that laws have no effect on criminals? Hmm, that's a crazy idea. Maybe I need to put down the jar and start thinking straight.

    I saw a video earlier today on youtube and it had that unmistakeable holy black sound to it.

    I had the very same thought about the black powder, and if it's so, there'll be a run on black powder as states scramble to pass laws. Funny, I'm shooting more black powder because of the current ammo situation; maybe tomorrow I'll be shooting my airgun because of the black powder situation. Here's hoping it wasn't black powder that was used!

    Commercial explosives--Pyrodex, black powder, smokeless powder and nitroglycerine based dynamite--make white smoke.

    Most military explosives--TNT, RDX, C4--make grey or black smoke.

    My first impression it was either a commercial explosive or a homebrew equivalent.

    The first reports over the past 48 hours have been contradictory. No shrapnel, then they were pulling ball bearings out of victims, then a doctor told the press it was metal fragments.

    In the first stages of an event, releases will withhold info that could only be confirmed by the perp, while deliberately false details which would be repeated by false informants and these compulsive confessor types will be leaked, so authorities can filter reports they receive in the course of an investigation.

    If you have reports more than 20 hours before when you posted, then you are about to become a person of interest in the bombing. That you could have reports of the makeup of the bombs BEFORE they went off is scary.

    At least two of the bombs were in trash cans, so if the homemade Claymore mine theory turns out to be wrong, the metal shrapnel could be bits of the trash cans.
