Spend some time processing a 5 gallon bucket of 223 brass. He had tumbled it clean and sorted out all the non 223, or so he thought....
Turned out there was some mixed cats and dogs like 9mm and 308 in there. They easily get sorted out when roll sizing and dont break anything. It just takes time to clear the jam.
But when a case that has a bullet rolling around inside makes it to my automated Dillon 1100, bad things happen. Like broken decapping pins/dies.
Luckily I had another toolhead with an FW Arms universal decapper so I was able to finish up, but the decapper was a total loss.
The silver lining in all this was that FW Arms has a new decapper out. I set it up and ran a bunch of GI 5.56 brass through today and it worked better than the old version. No primer pullback and the random bullshit Norma case with the small flash hole didnt phase it one bit.
