How about tellong us a bit about your gongs.
What's it made off?
What size do you use?
How far do you shoot at it?
How is it hung?
Problems and tips.
Here are some of mine. Some are mild steel 15mm to 24mm thick. Others are AR500. It is easy to see which is which. Tip 8mm mild steel is too thin!!!
I use sizes from 6"x6", 12"x12" up to 14" round gattic covers.
Hung with chain on some gongs but find conveyor belt rubber better to withstand the odd stray bullet impact.
I mainly shoot at hunting distances for practice. ie from 400 to 1000 yards. Sometimes further.
The rubber mounted behind the plate is protected from schrapnell fragments.
8mm Mild steel plate is no match for a .338WM at 400 yards.
19mm mild steel holds up much better at 440 yards from the same .338WM.
Large nuts welded to Rheo bars make good pivot points for cross bars to hand a gong off. They swing free and easy.
A 6"x6" AR500 gong hung off a saw horse and tent ropes to stabilise makes a good light weight portable set up.
