Good afternoon Lady's and Gent's. I have a question? Can someone tell me how mush Antimony i need to add to 20lb of stick-on wheel weights? I have 5lb of Super Hard Alloy Nuggets witch are (30%-Antimony, 70%-lead). Thanks

What are you loading for? How fast do you intend the bullets to be?
Sorry, but we need more info.
Same comment as BNE, but you will also need some tin in your final alloy.
I can tell you where you download a free lead alloy calculator :-)
http://castboolits.gunloads.com/show...oy-calculators
It's an excel sheet with lots of built in math functions to do the work for you. If you don't have Microsoft Excel check out Apache Open Office, the Calc program in that free office software can run the calculator.
The reason for the questions on what is it for is because a muzzle loader you would add nothing a 2000 fps rifle round you could want around 5 or 6 percent antimony. A 45 ACP might only need about 2%. And yes some tin would really help. But again how much depends on use for the resulting lead alloy.
Please furnish MORE info as stated above. Sorry - my crystal ball is cloudy today.
As with the others more information on what kind of alloy you want to end up with would be helpful?Quote:

For a 94/3/3 alloy add 2.1 lbs of nuggets and .6 lb tin.
Hey Banger, good to see you "back on the line" so to speak. Don't hurt the poor fellow. Only his second post, need time to adjust to all of us cranky old guys :-)Quote:

This is from my calculator that's BHN specific. Using 6.5BHN for stickons hardness add to your 20 lbs-
9BHN- add 1.9lb Superhard, and 7oz 100% tin to get 2%.
12.5BHN- add 5.1lb Superhard and 8oz pure tin. (Great for almost all handgun and many rifle calibers).
15BHN- add 8.1lb Superhard and 9oz pure tin
16BHN- add 9.5lb Superhard and 9.1oz pure tin.
If you have tin sources that aren't pure, such as 63/37 solder (63% tin, 37% lead) just divide the tin required by the tin percentage of the solder. The first example calls for 7oz tin, 7 divided by .63 = 11.1oz of 63/37 solder.

el34 Thank you for the great tip on how to work with unusual tin solder percentages. Now that we have a method of blending reclaimed solder from scrap, it will give us a much easier method of converting that to a useful number. I added that to my "cheat sheet" on bullet alloys and hardness. Thank you for taking the time to post the information.
