Thread: Cerrosafe

Does anyone on here know if I can purchase Cerrosafe here in New Zealand to do a chamber cast?

Failing that, what other ways to do a chamber cast. Could you coat the chamber and bore with oil and use epoxy?

Cheers,

Michael.

Lead tin or solder? all higher melting points but I dont see that as an issue as long as you can melt it?

At least with Cerrosafe you know the cast will be the same size of the chamber when cooled. Which I'd imagine is the whole point of the exercise.

Would a solder cast shrink when cooled? If it is a different size to the chamber, what's the point in doing the casting?

Easier to get a gunsmith to do it or buy Cerrosafe from Brownells.

Higher temperatures make getting a good wrinkle free cast difficult, epoxy might work but I did one using candle wax as an experiment which seemed to work ok.

I dunno I have never used cerrosafe or cast a chamber but when I have cast other things generally the shrinkage is in the center and the outside stays the same as when casting projectiles?
