Back when I could buy 500 cast and lubricated bullets for 16.99, (2006) no it wasn't worth my time. Now those same 500 bullets are 45.99. Yep it's worth it. Ohio was shotgun slugs only for long guns when I started casting slugs. Loaded slugs are over a buck a round for cheap stuff. The good ones are even more. I hope my heresy is excused here.
At a buck or more per round practice got expensive fast. I started casting slugs and buckshot. Now that I have scrounged a half ton of lead and the cost of cast bullets in 9mm or .357 are out of whack I'm casting them too.
