Personally I like swingers and I always keep in mind that there are still parts that will give you ricochets.
That is why I always try to place them close to the berm and keep them a safe distance from me. ......
One time at a public range, there were a couple of younger guys next to me that were shooting a steel target that I had never see. It had a stationary torso front silhouette of a peson and a center swinging steel rectangle. It was placed about 20ft. in front of them. Every so often I kept feeling something hit my leg. The hit was light so I did not notice it right off. Told them about it and then I moved to the next bench.
Yes, placement is crucial in the use of steel targets.
Be Safe !!!
