Again I appreciate the input, I realize my mistakes with heat, the mold was a bit too cool, and the melt maybe a bit too hot and my rytheme non-existant which affected the tmeperature of both possibly oxidizeing my tin out of the equation. It's been a while since I've visited but not many boolits are made during deployments; I'm getting ready to go home and get back in gear.
You mentioned oil or other contaminants, I highly doubt the initial degreasing boil, and 3-4 runs I did have seasoned the mold much at all. Does the downtime between casting sessions affect the mold?, and is it possible to clean the mold too much or too often? I felt it would be safe to go ahead and boil/degrease my molds when I get back may do the same with my pot to get rid of any residual dross build up off the pot walls. I read that time should have had some significant impact on the hardness of the bullets previously cast I may remelt them for fun so I have uniform bullets when I start reloading in mass; or would you think that unnecessary?
