Thread: help setting up a shooting range

so i have the land to set up my own rifle range, max distance i can get is 240 250 meters, i have the idea of setting up building a solid timber shooting bench and having steel plate targets at 50 100 150 200 and 250 on 100 x 100 posts but i'm open to what you have done and any advice etc. i have found shooting 10mm thick steel ok but the bullets tend to rip it up over time as i used to shoot it then just spray it black and re paint a red dot on the black plate seems to work well but maybe 15mm thick would stop this ? any advice would be great or pictures what would you do ?
