I have had good luck with casting chambers. If you are not happy with the results pop it out and pour another .The first will warm the barrel and make the second throw better . it doesn’t have to be perfect just full to get accurate measurements.I drive mine out as soon as I feel that it is solidified usually less than 5 minutes. I use a lyman lead ladle and pour directly into the chamber with barrel still in the action.

“The casting will take only a very short time to solidify, usually within a minute. Wait 30 minutes and then remove the plug from the bore. Turn the muzzle upward and the casting will fall from the chamber.”

From my experience, waiting 30 minutes will end up with you needing to use a heat gun to melt the Cerrosafe out of the barrel. You CANNOT pound the casting out of the chamber.

More like a minute should do IMHO.

Go to your local hardware/garden store and buy some sulphur/sulphur powder. Melt that and use instead. Dirt cheap and works well.

I have used Cerrosafe to make castings and my tips are:
1. Remove the barrel from the action. This makes the pour easier. If you don’t it is really hard to pour thru the action and is a bloody mess!
2. Pre-heat the barrel for 5-10 minutes in the oven on bake on the lowest setting, 170F in my oven. Allow to cool for a couple minutes so you can pick it up and it is under 120F.

This allows the Cerrosafe to stay as a liquid as you pout the casting. If you don’t, the Cerrosafe will solidify on the sides of chamber were it lands and block the flow, giving an incomplete casting.

I HAVE HAD PROBLEMS GETTING THE STUFF INTO THE CHAMBER BEFORE IT STARTS TO SOLITIFY.USED A PREHEATED METAL FUNNEL OR SPOON AND IT STILL SOLIDIFYS WHEN IT HITS THE RIFLE METAL .
