arkypeteI use a butane lighter held close to the mold cavity. Cheap, fast and it works.

Lamara good mold doesn't need a release agent.
some 20$ piece of junk might need some help but even those don't need a release agent.
if you can't get a bullet to drop from a mold it was cut wrong or it has a burr.
after a bit of use a mold builds up a patina [oxidization] that acts like a release agent all on it's own.
on a steel/mehanite mold the cavity's turn blue.
on brass molds they turn brown, and aluminum molds haze over.
generally 4-5 heat cycles on the aluminum and brass molds is necessary.

What he said.
I have close to 50 molds, maybe more, and use mold release on none of them. I tried it when I was first casting and didn't like the residue it left.

this! although i pre heat the alum ones by placing em directly on the pot full of melted lead for a few minutes and generally the first ones drop ready to go.

JJBonly mold release agent i've ever used with my old lyman molds is a wooden hammer handle.... a couple of quick smacks on the hinge pin of the mold handles and the bullets fall right out...............

res45I have a couple molds that like to have a butane lighter run over the cavities on occasion other than that I don't smoke the molds or use any mold release.
