Our local LE rents some of the pits at our local range for training. The trick is to get in there the next day and clean up after them.
Over 5k pieces and counting.
All processed and ready to load.
Thats how you do it. When the secret service uses our range, they don't leave anything behind, but when the police and sheriff's department use it for training or quals, they leave all their brass for us to pick up. We also have a local manufacturing plant use our range for load development. I like it when he comes, because he leaves once fired starline brass for us to have.
