Cheap reactive thermal target. Amazon Winco 12”x18”x1” polyethylene plastic cutting board. Black parts on the board is foil. Have about 80 rounds in it and will show impacts for 10 min plus. They have 1/2” for $7.50, not sure how long the impacts would last on a 1/2” thick board but for $7.50 kinda hard to beat.
