After four days in storage (more than required for a typical Boomershoot event) the mix looked like this (click on a picture to get a high resolution version):
I used the dead tree to hold the 7″x7″ target while doing sensitivity tests. This was after four days of storage. Multiple hits of a .22LR with a target velocity ~1170 fps failed to detonate it. .22LR with a velocity of ~1500 fps detonated it on the first shot. At the time of mixing 1170 fps would reliably detonate it. The top of the tree was moved rearward and caught by the live tree.
I put four reactive targets on top of four IPSC targets to make it easier to find the targets at 700 yards away. I also hoped to be able to do my own long distance spotting by moving forward to the targets and see bullet holes in the IPSC targets. I was not able to do this. There were no bullet holes to be found after firing one shot at each target from 700 yards away.
The 50 grain VMAX bullets, with an estimated target velocity of 1970 fps, were successful in detonating the targets. I had not anticipated all the plastic scraps. I will return to pick them up. I ran out of time and had to leave.
I have video of the target detonations which I hope to get digitized sometime this week. In the scope I saw a bright red flash as the targets disassembled in a cloud of smoke but I don’t know if it showed up in the video.
I did not have enough time to do the last test–Boomer Clays. I did get various types of high velocity shotgun ammo that at least has a chance of working. Those tests will have to be another day. Perhaps this Sunday if the range work and rock blasting goes quickly.
