View Full Version : Casting with Bismuth

I see that bismuth melts at 520 degrees. I also know that its density is close to that of lead - thus its use in shot loads.

So, is this stuff brittle? What about alloys?

I was just thinking it may be the answer for hunters in need of non-toxic boolits - that they can cast themselves....

I seem to remember a thread on this a while back. I don't remember what the verdict was, but someone in the know commented on this. You might try the search, it might turn something up...

look for an old post by Floodgate. He does not post here anylonger but can be foudn at the Antique Reloading Tool Collectors forum. Or you can pm me and I will forward contact info. He did a bit of work with bismuth, both casting and swaging.

Thanks. I was just curious. Fortunately for me, lead is still just fine where I hunt.

I posted before Bismuth very hard and brittle had to mix 50/50 with tin to get to act like linotype when hit with a hammer. I used a Lee .44- 310 mold and they came out at 240 grs.

Hmm, tin and bismuth is still non-toxic. Actually, that might make a good business venture if the lead-free "stuff" spreads. I certainly hope it doesn't... the tin and bismuth are quite pricey compared to lead alloy.

I wonder how your 50/50 alloy shoots compared to a copper bullet?

Does it drop from the mold the correct size? I mean for the mold... equivalent to lead.

More on the subject here. http://castboolits.gunloads.com/showthread.php?t=63144 I find that Google does a better search. 50/50 bismuth/tin One 200gr cast bullet would cost $.34 each if you go by Rotometals prices per pound.

I dunno.... He seems to be still here, I just mostly see him in the "casting for shotguns" forum. Several times this month and just day before yestiday.

Bob,

Floodgage does visit but is not as active as I would like to see. He is a great resource and a good guy all around. One thing to note is the ARTCA website and forums are down for re-construction and a person has to have someplace to go, and here is as good as any.

Stepson told my that at 50 feet on a swinging 1/2in. plate they put a 3/8 in. dent in the plate.
When two hit in the same spot they opened a hole in the plate.
