I recently purchased a portable reactive target system from Challenge Targets and gave it a good "shake down cruise" out at my gun club. I'm very impressed with it and particularly enjoy how truly portable it is and easy to take down and put together.
I pushed it to its limits by blasting it with 10mm Buffalo Bore 220 grain loads, full power stuff.
NOTE: I did not receive any compensation or incentive for making this video, just purely interested in reviewing it. I recommend it to anyone looking for a way to do steel plate shooting with portable, and affordable, gear. I bought the targets, etc.
