How does "too much tin" appear to you? Does it change the way the bullets cast? Does it physically show up in the melt?

I'm no metallurgist, but I don't think you can "skim off" the tin from a lead/tin mixture without some chemistry involved.

You can certainly "burn off" the tin by heating it too high, but once tin is alloyed it tends to stay that way.

WW's don't have a lot of tin, that's why WW have to have tin added to some mixes to get the alloy to fill out molds properly.
