We have two sets one is for Pistol and one is for rifle.
they are all made of 1/2 rejected or scrapped med high carbon steel.
The pistol are 6 inch disk hung from 2 chains so that the face is close to 20 degrees down they are set up at 30 yds.
The rifle are disks of the same material hung the same way a 20 inch a 10 inch a 6 inch and a 6 inch cut in half.
Some points: they have at least 18 inches of chain this and the angle helps absorb the impact.
The angle also helps deflect any ricochets into the ground.
All the rifle gongs are set up at 250 yds, some of the cartridge guys like to shoot them to and it helps keep them from getting torn up.
We have been discussing setting up some animal targets with a hole as the vital area and putting a gong in the hole and scoring them hit or miss.
Do you think the guys would like that? Lee
