Sold by the Ingot ~ i.e. 1 Pound
This ratio of~  87.25% Bismuth, 0.75% Antimony  and 12% Tin is the best ratio we have come up with as a substitute for lead. This alloy melts at about 395 F and is best cast or poured at about 500F. Testing the hardness with a Lee Hardness Testing Kit, we came up with an average of 19.3 on the Brinnell Hardness Scale, although there was a range during the testing.

The bismuth gives you the weight (as close to lead as possible) and the tin helps holds it together and makes it less brittle.
This is an alloy we have been asked to make a few times so we decided to make a larger batch and have it easily available to everyone. As we are still testing this alloy, we are offering it at a lower cost and asking customers for feedback and their thoughts on how it works. Yes, we know it costs way more then a lead version, but hopefully with more volume, we can offer better prices in the future. One item of feedback we got from our customer follows:
I have some results from shooting this alloy over the weekend, very favorable in the limited testing I did.  Accuracy and high velocity is not a problem if the bullet fit to the rifle's throat is right.  No bore fouling, no problems at all.  I even cleanly killed a small whitetail spike buck with my .223 Saturday using the alloy you sent. 
I documented the entire work here on this bullet-casting forum,  Load information, approximate velocity, and target ranges are in the text with the appropriate photos.  Link to the forum thread  

@ 2400 fps in my 30'06, but has lost 29% of nominal cast bullet weight

    I’ve had a lot of success casting bass jigs from this alloy. They hold a powder paint well, and they fish just as well as lead jigs.

    I used the alloy to cast 1/32 and 1/16 ounce fishing jigs. The alloy is very brittle compared to lead. More time is required to clean up castings compared to lead but the final product is of high quality.

    It seems to work great for casting. I have used it so far for casting round balls for muzzeloader and it works great.

    Bismuth Tin Alloy For Fishing Lures & Weights

    Posted by Dale Wyman on Feb 28th 2021

    If you need a Non-Lead alloy for fishing baits, weights, jig heads etc., this is the alloy I would suggest. I use the alloy for blade baits, drop-shot weights, jig heads and more. I use a Lee melting pot to pour into my Do-It Molds and the alloy at just over 300° F pours perfectly each and every time. Super fast delivery!

    Bullet Bismuth

    I use it to make jig heads for my customers at Glasswater Angling as we are a lead free, non lead, fishing tackle company. It provides a specific gravity close to lead and is very easy to work with. I have gone through 15lbs of it (over 2,000 jig heads) and have found it consistent every time.

    I have been using the Bismuth Tin alloy to pour all types of lead free jig heads and blade baits in my molds from Do-iT Molds. Its a perfect alloy for this purpose!!!

    Lead free alloy

    I bought this alloy to cast for muzzleloaders and shotgun for hunting in an area that prohibits lead. So far it casts well but definitely prefers lower temperatures than lead alloys, and casts better in colder molds.

    Lead free bullet alloy

    It's more expensive than lead but not nearly as hazardous. Good finished weight and melts without a problem. I bought 15 pounds and it came in a few days, less than a week. Good stuff!
