So I have this small hunk of gold that i melted down and I want to mold it into a 5.56 bullet and have it loaded into a case. I'm not gonna shoot it, its only for kicks. Anybody? Anybody?

Interesting. Got a Q for you Matt, at what temperature does gold melt at? Just wondering how hot gold has to be to melt and at what temperature the molds might either warp or melt themselfs, do you know?

Sorry I cant be of help, just have 38 swc and ball and minnie for 45 black powder. But I have to say that you need to take pics once you made this dummy round.

Not in America it don't!
It melts at 1947deg here in the good ole US of A.

maybe better to melt it in a mold as a rough cylinder then machine it to spec. I'm not thinking your traditional bullet mold is gonna hold up.

I haven't done anything with bullet molds but what are they made of? I would assume they are some type of steel or iron. If they are cast iron they have a melting point of 2300degF according to this website. The thing I don't like about the website is that alloys have a melting range instead of a certain point. That would include the gold as well. I think I would have to agree that a bullet mold probably wouldn't hold up well. Just my $.02.

Metalurgically speaking the metals have a "Range" of smeltable temperature based on the Eutectic State of the material being smelted.... the Eutectic range of the material is the range in which it is in transition from Solid to Liquid... the metal melts at a lower temp but is not "Flowing" yet... that is where it is sort of a paste..... Gold can be potted and cast at a temp where the bullet mould can be used, you would have to melt it and flux it in a pot then pour into the mould the mould needs to be heated to keep the bullet from being Wrinkley... Even with aluminum moulds you have to heat them to almost the temp of the melt.... I have been casting my Sharps lead for a while now... and some pistol leads too specifically for my C&B revolvers...

how much is a chunk of gold that size worth? Around a grand or so?

A .22 bullet mold wouldn't be a traditional spitzer profile anyway.
