The perfect target

Ok, i started like everyone else with tin cans. Decided that i needed a smaller target so, i drilled a golf ball and hung it on a string. Worked great in helping with smaller groups but when hit you never knew where the ball would go. A couple times right back at me. Needed some thing softer. Stole a hollow rubber hockey puck from the grandkids. Better, but still some bounce back. Got this idea to take a tennis ball and drill a hole for string and cut it like an orange. Wala, works great, mo more bounce back and only 3" in diameter, perfect target.
