CCI Blazer 158 LRN .38 Special has a muzzle energy of 200 ft lbs.
I was using that to test my homebrew resetting knock down target (version 1). I was afraid it would not stand up to the beating. What I found was that it would only knock it down with springs disconnected and hitting high on the target.
Here are the reasons I think it failed my expectations
1) Too much slop in the system eating energy. 1/2 conduit would not go though the 1/2 tee so I used 3/4 ... that is a loose fit. Also the landscape timber might be moving in the concrete block. I tried to wedge a 2X4 in there as well, but can do better I think.
2) I might need to lower the pivot point so it turns easier.
3) maybe just too heavy
I have some ideas for version 2 that should be simpler.
