Hahahaha...in a few hundred years, they are going to excavate my place for whatever living accommodations are around by that point...and they will find so much brass that by the time they bring the experts in to analyze everything there will be an hour long documentary on the unrecorded great battle of SE Oklahoma in the early 2000's.
I actually bought a brass catcher because replacing some of these harder to get cartridges is getting to be expensive.
Every landowner I deal with would gladly trade a dozen pieces of brass on the ground that they'll never find (if you could, I wouldn't need a brass catcher) for the pock marks to stop appearing across their pastures.
