There are numerous trimming jigs for making 300 Blackout brass from 223 cases. Most are for the mini chop saw Harbor Freight sells. I had used that chop saw for a day until it smoked and fried on me. Took it back and got the next size up in chop saws. The typical cutting jig worked, but the cut off brass ends would get jammed in the vise on the saw. I'd have to stop to clean the brass ends out every 20 cases. I decided to make a jig that will send the ends out of the way using the bigger cop saw
