View Full Version : Normal? Ask the experts on Cast boolit!

As well as having my own stash of lead, the guys at the local transfer station save out lead and give it to me. When I smelt it down the ingots it produces are usually nice and shiny and the boolits cast from it are bright and shiny.

A couple of weeks ago I smelted down a 5 gallon pail of wheel weights. The ingots from the wheelweights are a dull gray and the boolits cast from the wheel-weight alloy have a satin sheen to them.

Par for the course? Is this what the rest of you experience or do I have a strange batch of wheelweights? AFAIK casting temps are the same, again, I stress, the ingots are different as well as the boolits.

Do you guys cast straight wheel weights for your rifles or do you mix it 50/50 with lead?

One possible reason for the dull grey is because of a near zero tin content.
Probably the fact that there is some antimony content may contribute to the satin finish.
I always have a sorta satin cast with 92-2-6 when the molds are fully hot and the 20 to 1 alloys are more bright and shiny.

Agree with LWKnight's comments/analysis on probable alloy composition. Yes, par for the course. No, not likely a strange batch.

I usually pour straight clip-on ww lead. Works very well. But 50:50 WW:Pb also works well for many applications. Speaking generally, it's hard to go too far wrong with either. Good luck.

Send it all to me for testing. :kidding:

Send me half and you will get the testing done twice as fast. Wilco needs some help in the testing realm and I have the time. :bigsmyl2:
