Just to clarify, I think he means 50:50 pure lead to wheel weights, and not 50:50 solder. That dilution of wheel weight alloy is not an uncommon mixture if you are trying to limit the antimony content of the mix for bullets you will use in extreme cold. Wheel weights are known to shatter in extreme cold (all sub-zero) because the antimony (up to 4%) is too brittle in sub-zero temperatures.

If you just want to shoot more conventional bullets, you can get into the ballpark of mimicking Lyman #2 alloy by adding 5% pewter by weight to melted wheel weight metal. This alloy may end up with a little more tin than antimony which means that if you try to water quench it hard, after the hardness peaks (around 2 weeks aging) it will then drop off again over a year or so. Bullets with less tin than antimony can remain hardened for a very long time.
