The Fireforming .450 GNR video I promised

It's not instructional, just showing a concept of technique. There are easier and more efficient methods, like FL sizing .50 AK brass. But it just shows what a little ingenuity can do. I'm still learning how to make videos and use software, it's just fun for me. I've done this on many cartridges. Some old timers use fillers with a very light load, it could be catastrophic with heavier charges, I don't like it myself. You are on your own.
