Will i get a bigger boolit in size when i run my pot and mold to Hot are to cold thanks [smilie=b:

Too cold - shiny & wrinkled, Too hot - frosty. Biggest boolits probly when 700 degree alloy makess slightly frosted boolits (manipulate mold temperature). Heavy frosting causes led to pull away from mold as it cools (lead touching mold doesn't freezeand whole boolit shrinks instead of pulling molted lead in from sprue puddle), - smaller boolits despite mold expanding. Cast with mold heater to control mold temp.

It depends.

Maybe yes. Maybe No.

Thanks, Williamwaco.
That link (think you've posted it before) goes to show that, like so many other aspects of casting boolits, there are very few definite answers, and almost all of our sought-after information will only be gained by experimentation.

There's a lot to be said by just doing it. Best way to learn.

Mold cavities shrink more when too hot, smaller boolits!

Some member here has the signature "Everything is a guess until you pull the trigger."

I have found that you can almost never be sure what is going to happen until you try it.
