I want to build a 1000 yard gong.

msg.drew your plates are pretty thick. This makes them "clunk" more than "ring".

At longer distances, bullet speeds at impact are lower, and the damage they do to steel falls off spectacularly as impact velocity falls. I once shot standard Palma ammo (#2155 Sierra at 3000fps muzzle velocity) at three different identical mild steel 1" thick plates, at 400y 600y and 800y. The 400y plate was gouged (perhaps a quarter inch deep), the 600y plate was gouged but the depth was barely noticeable, the 800y plate was literally undamaged, all that was present was a grey splash mark that disturbed the paint.

So for longer distances, you can use thinner plates and still get good life out of them. Using thinner plates also allows you to make them bigger in size, for the same weight and steel cost. Not only is this easier to hit, but they should ring better too.
 
rather than using chains, which do get hit, i use a piece if 2" x 3/8" (or thicker) flatbar welded to the backside. put a hook on the top of it and a corresponding loop on your frame. pretty much indestructable that way. should add ...weld the flatbar on edge so the slim profile is harder to hit as well.
 
If only you lived closer!!

order a plate of good steel from the metal supermarket, like 12"x12"x1", should be fine. plain carbon steel should work
 
Just a ball park how much is a setup like this gonna cost + i hope u guys got a atv or else your gonna #### up your back draging that ackward peice of metal out there.
 
What has this thread got to do with match results? Give the admins a break and post your stuff where it belongs!

My 5/8" plate at 400 yards is dimple free with 308 amax and match bullets from about 2500-2900fps

Fast forward to about 30 seconds in first shot is at 43 seconds... five for five hits see what I mean about it making more a thud then a ding my plates are very thick.
