    The sad thing is you may try time after time and suddenly the problem disappears without you knowing why. A little lino (to harden and fill out) added will likely help. Once you get the melt level down in the pot, a good scraping of the pot surfaces should float what contaminates are left.
    The speed you fill the mold and actual mold temp will be close to your past experience. Changing to a bottom pur doesn't alter that..
    Information not shared. is wasted.

    Another thing to remember with a new mould is it make take being heat cycled 3-4 times or 3-4 casting sessions to "break In" and cast its best. This break in is some burning impurities out of the blocks and more developing the patina that helps them cast so good.

    Likely that the marks you see are from the towel or whatever you're dropping the boolits on.
    A deplorable that votes!

    After the though cleaning that you do with Dawn and Acetone soak, it takes 2 or 3 casting seasons to develop the patina that gives good boolits.

    Heat the mold up and cast a few boolits till wrinkles are gone, let the mold cool down and repeat.

    The third casting session should give good boolits after the mold gets up to temp.

    Preheating the mold on a hot plate will help a lot in getting good boolits.

    Just staying at home and playing with multi-color boolits.

    I would clean up the mix again.

    It don't take much to make some bad ones.

    It sounds like heresey, but when a mold makes me have fits I'll spray the bejezus out of it with RemOil, and in a few more casts I'll have good bullets.
    I flux with a small piece of bullet lube or beeswax, stirring fairly quickly and deep, and throw a kitchen match in the pot to burn the smoke off. It works for me.......

    I cast a lot of range scrap & no issues. When I get a new mold, it does take awhile, even after cleaning, for me to get good bullets 100% of the time. generally fluxing often helps. For me during casting, that is just stirring often with a wooden stick or spoon. Sometimes adding just a bit of tin helps a lot with mold fill-out. I cast about 700deg.
