hahaha same here! what a pain in the ass. Nothing like a 15 minute task turning into 45... SMHUggh....that sucks. I was using stainless pins and wet tumbling. Problem was that the pins were cut the perfect length to wedge across the case mouth of my 6.5 Grendel, 6.5 Creedmoor, and 6.5 SAUM brass. Had to use pliers to remove pins on every affected case and then manually shake out all the pins stuck in the case that were captured by the wedged pin. The tumbling media you are using would have avoided that.
