Just had some fun with this stuff with the boys. I ended up mixing up 2 lbs and then pouring it off in to a bunch of perscription pill bottles. Turns out those smaller pill bottles full of this stuff is enough to disintegrate a cinder block! Pill bottles were about an inch wide (although I did have two a bit larger, maybe twice the capacity).
You have to hit this stuff to where the bullet passes all the way through it. First shot my boy made put a half of the bullet through the side of the first bottle and it didn't set it off, just spilled some out.
We dug up all kinds of things to blow up such as an old trash can, old bbq grill, couple of metal pans and a artsy fartsy flower looking metal thing.
To give an idea of the power of a small pill bottle, the first bottle was set up on top a steel 15 gallon barrel (the kind oil or thinner would come in). We put a brick on the barrel, and set the bottle on the brick. Exploded the bottle, it was unobstructed all around except for setting on the brick. It disintegrated the brick and blew the top of the steel barrel down in the barrel.
Taped one bottle inside the pot metal lid of a propane grill and it shredded the lid and the base. Taped another behind the front metal panel of that same grill and it shredded that metal panel and collapsed the steel legs of the frame. Another was placed inside an old steel 2 drawer tool box, lid shut. Completely blew the lid off and V shaped the rest of the tool box.
This stuff sure brings a great big smile and a lot of laughs to the boys.
For a rifle I had taken two, but we only used one. Took my M&P15a, but only used the one I put together which was a New Frontier Polymer lower and DPMS oracle upper. Pretty darn accurate rifle as most times we only had a one inch orange target dot to hit from about 50 yards out using a Truglo 2x red dot, the red dot ended up being the same size as that one in orange target dot. I was pleased with the rifle and the Truglo, I had used them together once before, but had removed the Truglo and put it on another rifle to try out awhiel back, then put it in the drawer. I just stuck it on today and tightened it up and it was still dead center. We rotated turns shooting and my oldest boy never missed a shot. Youngest boy got about 4 hits in as well.
