I made a newbie mistake. I found corncob bedding on clearance at my local pet store, so I bought it. Its was a larger granular than normal, but polished my brass really well. However, the pieces are now stuck inside my cases. I should mention that the cases still have the spent primers in them. Am I the only one who's ever done this? What should I do about digging out the media? Can I knock the primers out by hand and then go through the primer pocket? I feel like an idiot.
