Lyman #2 Bullet Casting Alloy

Lyman literally wrote the book on bullet casting, the first edition being published all the way back in 1980. In their book, they describe the perfect bullet casting alloy which they called Lyman #2. Nominally, Lyman #2 consists of 90% Lead, 5% Tin and 5% Antimony. The Tin provides great castability of the bullets, the Antimony allows the bullets to be sufficiently hard to prevent barrel leading. Many recipes are given to get whatever alloy you have to resemble Lyman #2. Bottom line, Lyman #2 is the best alloy to use for general bullet casting. is proud to offer our version which can be delivered right to your doorstep.


Shown at right is the current lot of our Lyman #2. As you can see, we have a very good supply. The store area of our site will give you the current total on hand. Don't worry, if we sell out, like Doritos, we'll make more!

Our Lyman #2 Bullet Alloy is cast in what is called "notched bar". This is THE best form to buy ingot in. If you have purchased from other commercial vendors, you've probably received a huge ingot that you had to remelt to get into your pot. Not so with our alloy. It comes ready to break off and use, just like a Chocolate Bar. Each notched bar weighs about 8 pounds, with each notch a little under 1.5 pounds. The notches are 2" square and about 1 3/8" high. Consider that you can break off as much as you need and put it right in your pot without any extra work when you are looking for alloy.  

Don't be confused. The Lyman #2 you buy from us is not some random home brew made by melting down who knows what. Our Lyman #2 is produced right here in Cleveland in an ISO 9002 certified foundry. Every bar we sell is stamped with the foundry mark indicating what it is. In this case, 5% Tin (Sn) and 5% Antimony (Sb). You'll always remember what you've got as it's clearly marked.


As mentioned, you can easily break off "chunks" to use in your pot. I've found that the best way to do it is to put the piece you want to break in a vise and clamp well. Put your body weight into it and push it as far as you can.

Here is where you need to be careful. This stuff is not like steel that you have to bend back and forth. Pull back on it the other direction and it will snap off. Get your foot behind you so you don't lose your balance. You won't need as much force to bend it the other way. Be careful!

The first time you do it, it might catch you by surprise. It's not easy to break, but it's not hard either. If you have a larger pot like the RCBS Promelt, you can stick the end in and just let it melt it's way down. The choice is yours, but you don't have to reprocess our alloy to start casting immediately.



We use our own in house analytical equipment to conduct a real Brinell hardness test. We don't rely on pins and hammers to test our alloy, we use the same formula that Johan Brinell came up with all the way back in 1900. To read more about that test and how we perform it, visit this page.

Our current lot of Lyman #2 tests at a BHN of 16.6

Test was conducted on various ingots, depressions measured, averaged and that indentation diameter used to calculate the hardness.

Specifically, we used 150 KgF force, 12.70 mm ball and an average indentation diameter measured with digital micrometers and a 40X stereo microscope of 3.362mm.


At the right is the actual lab certification of the current lot of our Lyman #2 alloy. This lot has Tin at 4.96%, Antimony at 5.02%, .12% trace elements, and the balance being Lead.

As you can see from the photos above, our alloy is bright, shiny and without contamination or dirt. When you get it, take a minute to admire it's beauty before you put it in your pot.

Make sure that you scrape your pot well as it would be a shame to contaminate this alloy with what was in your pot last!


We believe our Lyman #2 is the highest quality casting metal on the market today. With some vendors charging up to $2.60 a pound, we are pleased to be not only the highest quality source, but the lowest cost source.

We can ship up to 68 pounds of Lyman #2 in one flat rate USPS box. You will receive 8 full bars and a few pieces to get you to the 68 pound weight. Try our alloy, we know you'll love it.
