Those of you who built your own backstops, would you mind sharing some ideas?
I built mine from landscape timbers, backed up by some steel belted truck tires. The individual timbers can be replaced if/when they get too shot up. There is a plywood sheet hanging in front to make it easier to afix targets. It's got a bit of sway to help boolits dump some energy (at least that's my story and I'm sticking to it!). I've not gotten any return fire from 22lr, 9mm, 38spl, 357Mag, 30 carbine, ACP/GAP or .223. Range is generally 30-40 yards (depending on where I left the bench). At the bottom of the trap is a steel swinger and two of the orange plastic pivot targets.
It works well enough, but I'd like to recover more of the lead from it. Curious what y'all have built to make it easier to recover the lead. Looking for ideas in sand filled traps (not quite ready to build a huge metal trap (yet).
