Hi, tired of casting two 0.490" balls at a time I purchased a new Lee six-cavity 0.490" mold. This new mold gave me a chance to test the Frankford Arsenal Drop Out. A light coat of the Drop Out worked great. Good balls from the first to the ~500th were produced, no sticking of balls at all. Never needed to wack the mold to release balls, they just fell out.
In the past I have smoked molds with matches, candles, butane lighters, and even burning kerosene. None of those methods could hold a candle (pun intended) to the Drop Out in performance.
BTW, since such a light coating is required, a 6oz can of Drop Out should last many casting lifetimes. I got a little of the spray on my fingers, but acetone took it right off.
Regards,
Richard
