[Mr. 16 gauge]

Thanks for the replies, guys....

Yeah, the're cheap, chintzy, cheesy, flimsy.....but to a 20 year old college student with little pocket money that wanted to get into bullet casting, they were a Godsend!
I've used them for 30 years, and some are still going strong while others are starting to break down: halves aren't matching up perfectly, sprue cutters aren't cutting as cleanly as they used to, pins are coming out, ect.....so it's probably time to upgrade.
Still, for the original $15 or so I spent on the mold, I think I got my money's worth out of the things.
