Thread: 1000 yard gong

Hey im in the process of making some gongs to chuck out on the farm, Was planning to get quite a few mates around and we all stretch the legs to 1000y,
Was going to have 3 gongs set up from 500-1000y Was just thinking if anyone has done this and is there any good ideas just to keep it intresting will probably bring a few calibers, havent been to any proper set up ranges and wasnt sure if there is simple things that will make the day roll smoothly or little challanges,
