Well got out and cast some more pure zinc bullets today and 80% of them turn out which is pretty good but it's still a slow process for me at this point as I only use one cavity in my two cavity mold. Well later in the day I went back out and added some aluminum to the molten zinc that I had left just to see if I could get it to melt using the extra heat from the hand torch. Funny thing is I didn't need to at around 7-800 degree the aluminum melted in with the zinc just fine so I cast some bullets out of them and they turned out pretty good as well not sure on the percent but they looks close to the same as the pure zinc ones. Is there any plus to mixing aluminum in? just found it odd that the aluminum would melt in at such a low temp I'm going to play around with it some more maybe tomm and see how much aluminum can be added.
