I grabbed a citronella candle to use as flux. It took me forever to get good bullets from this batch of alloy! Temperature was the same 700 to 750 degrees as before (different mold, SAME batch of alloy) ,same casting technique was used as before also! Is there some thing in the citronella (oil) that could cause the wrinkles and poor fillout I got?? After the pot got around 1/3 empty, the bullets started to come out good. I did throw the wrinkled ones back to refill the pot. I've used this mold before with few if any problems. This is the 1st time for a citronella candle though!
