Reply To: What is your Backstop made of?
Here is mine. PVC Electric Box is completely weather proof. Steel plate in the back just in case, but the rubber mulch stops a 40 FPE 25 cal no problem at 2ft during repeated chrony work. I’ve probably put 1500 rounds in it without changing the mulch. Its getting a little heavy, so probably getting close to time to empty the lead out. About $30 total. Need a drill and hole saw to open up the front of the box.
