Went to the range this morning to try some loads and a guy was shooting a couple of AR's. One was a Grendel the other was a 243. As I went to set up my bench, he had to of went through three 10 round mags of 243. The barrel had to of been extremely hot as fast as he went through the mags. The ground was covered in brass all around his bench so he had been shooting a while. When he left, he threw the brass in the trash. Heh, heh, guess who went dumpster diving!!! I got 80 rounds of once fired Hornady Grendel and about the same in Federal nickle 243. Goody for me and I don't even have a Grendel.......yet!! The funnest part was he drove to the bigger dumpster and threw away the box's that the rifles came in. They must have been fairly new rifles. Guess he was breaking them in.
