Thread: Who has built a heavy duty cast bullet trap ?

I should point out that my steel trap was designed for 10 metre indoor use in my workshop where it performed admirably, but would not be so flash out in the weather. I think Cordite's tyre and gong set-up is a better all-weather solution, and a lot easier and cheaper to make. if the gong was at least 25mm and made of Corten or similar hard steel it would work well. Do not use mild steel as it pocks badly (even with straight lead) and can send bullets and fragments right back at you. I once had to dig a .30/06 jacket from my forearm 80 metres from a mild steel target, and I have been struck with lead pistol bullets/fragments at 15 - 25 metres many times.
