CERROSAFE® CHAMBER CASTING ALLOY Reviews & Ratings

There are various products on the market which can be used to make a cast of a gun chamber. To be certain that the product we are offering you is the best and most practical, we contacted the basic manufacturer. They recommended Cerrosafe because of its unique features. Unlike Woodsmetal which swells upon cooling and cannot be removed from a gun chamber, Cerrosafe shrinks during the first 30 minutes of cooling and then at the end of an hour, is EXACTLY chamber size. At the end of 200 hours it will have expanded approximately .0025'. This factor is well known by all toolmakers and they will take it into consideration when making dies or reamers or gauges from your cast - if you will tell them the cast is of Cerrosafe. Cerrosafe melts between 158° - 190° F. It should be melted in a clean, iron ladle. Source of heat should be removed as soon as the alloy is completely melted, at which time it is ready to pour. The solidified casting should be removed from the chamber before, or when, it cools to room temperature. If allowed to remain in the mold over an hour, it will grip the chamber walls and be difficult to remove. Clean the chamber of the rifle thoroughly, then plug the bore immediately ahead of the throat with a small rag - but not so tightly it cannot be driven out. If possible, pour the molten Cerrosafe through a small tube into the bottom of the cast, gradually removing the tube as the chamber fills. If the barrel is cold, warm it to room temperature or above before making the cast. When cooled, remove from chamber, using a rod or dowel from the muzzle end of the gun. SPECS: Sold by weight. Alloy. Infinitely reusable.

Inspection of the bore of rifle is a mus

This product will work if you have a good barrel without in perfections. It will give favorable measurements of a an 1/2 to 1 inch, provided dont have a barrel issues ,like I did . As a diy person. You need to have a gun smith inspect the entire length of barrel with bore scope. For If the barrel is badly rust pitted the casting will not come out once its cooled down solid. If you try a cleaning rod in a pitted barrel it will bend or break, doesnt have the strength to shear the cast from the rust pit. Or if you are not aware of a damage in the barrel ,and pour a casting in that exact area like I did the cast will not release. Best to heat the barrel with heat gun and melt it out. Dont use anythlike wooden dowel will break ,or a steel rod like i did. , use a slightly smaller brass or aluminum rod to remove, very carefully, if not dont do it ,melt it out. Thats what experience was , dont want you to have to go though, what a diyer like me had to . After your done have the barrel inspect for casting flash ,you got to get that out of there . That my experience best have a gunsmith do that has tools for this.

Be careful

Follow the directions exactly, waited half an hour then proceeded to destroy a cleaning rod trying to remove it from the chamber. I'll have to heat it with a heat gun to remove it from the chamber and buy a new Dewey rod. Not sure exactly what went wrong. I'm hesitant to try it again.
