Candle smoke, other than that I use Frankford Arsenal "Drop Out".

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

a 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.

Games played with the ball and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be the constant companion of your walks."

I don't use any release agent on my steel nose pour mold.

only 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...............

I 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.
