This trap works very well for low velocity target .177 pellets. The two swinging steel targets are easy to see and respond nicely to pellets. The supplied paper targets were cut too small to fit the trap but printing targets onto card stock and cutting to exactly 7" X 9" works very well. The hits are somewhat noisey.When I tried this trap with a higher velocity .22 pistol the swinging targets became badly battered. The .22 pellets dented the back of the trap and many richchet out. This trap is NOT recommended for high velocity CO2 or hunting type guns!
