In the local (with in 200mi) 15 Rhondys every single one has swinging steel for targets. Rifle from 50 to 100+ yards Pistol 30 to 75 yards. These are all on trail walks. Many have also started a derringer trail. Standing still on paper at a known distance is alright, but I enjoy moving from target to target at a different distance a bit more. Seeing the target swinging gives a person immediate satisfaction.Paper, steel, and old bowling pins.
I sight in using paper targets, but for fun I shoot steel targets that I made. I bought the clangers from Walmart, and made a frame from old rebar and some chains I had in my tool shed.
Our club always has old bowling pins hanging on strings. They're a lot of fun to make dance.
