I’ve done it a lot. It’s not my favorite thing to do. It’s much easier to buy it already converted. It is very labor intensive to convert it without using a really expensive Dillion and ammobot setup. Plenty of YouTube videos of people cranking them out that way. I consider it like most aspects of reloading. I use it as a hobby. The more I can do myself, the better. Casting my own projectiles, my subsonic 300blackout is reloaded for about $.08 each. My brass is free. Small rifle primers are $.03 each. $.03 of A1680. And about $.02 in lead and powder coating. Of course, since it’s a hobby, I don’t consider time spent as a cost factor.
