Product no.: 080027050

050806011892 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.

Experience Precision with Cerrosafe® Chamber Casting Alloy

The CERROSAFE® CHAMBER CASTING ALLOY from BROWNELLS is the ultimate solution for creating accurate casts of gun chambers. Designed for repeated use, this alloy is a must-have for every gunsmith.

Never Wears Out - Use Over And Over

When it comes to chamber casting, not all products are created equal. We have sourced the best option available directly from the manufacturer, who highly recommends Cerrosafe for its exceptional properties.

  • Unique Shrinking Feature: Unlike Woodsmetal, which swells upon cooling, Cerrosafe shrinks during the first 30 minutes of cooling, achieving an exact chamber size after one hour.
  • Expansion: After 200 hours, it will expand approximately .0025", a critical factor that toolmakers consider when crafting dies, reamers, or gauges from your cast.
  • Melting Point: Cerrosafe melts between 158° - 190° F and should be melted in a clean, iron ladle.

To ensure optimal results:

  1. Remove the heat source once the alloy is completely melted and ready to pour.
  2. Remove the solidified casting from the chamber before it cools to room temperature to avoid gripping the chamber walls.
  3. Thoroughly clean the chamber and plug the bore with a small rag before pouring.
  4. If the barrel is cold, warm it to room temperature before making your cast.

For best results, use a rod or dowel to remove the casting from the chamber, starting from the muzzle end of the gun.

Not recommended

Brownells USA Be careful 21/09/2018

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.

Brownells USA Works as advertised 09/05/2011

Following directions is a must with this. If you get is stuck, put the gun in an oven at 200 degrees. Stuff comes right out.
