These are excellent.
Used with the hooks the sound when hit is easy to hear.
Have them in 4, 6, 8, 10 and 12 inch
I use these 1" gongs on pvc frames at 21 yards, 33 yards, and 48 yards with iron sighted .22 rifles shooting CCI ..22 Long CBs. They work great on my home range in the trees to keep me sharp. Thanks, Brad.
