Swaging, rather than casting, became a preferred manufacturing technique during the 19th century industrial revolution; but cast bullets remained popular in early rimmed black powder cartridges like the .32-20 Winchester, .32-40 Ballard, .38-40 Winchester, .38-55 Winchester, .44-40 Winchester, .45 Colt, and .45-70.Disadvantages became evident as loadings shifted to smokeless powder in the late. However, improper handling of the investment powder often destroys their efforts. Improper storage, poor water quality, wrong mixing ratios, insufficient mixing methods, uncontrolled temperatures and others can each reduce casting quality and thus cause loss of production and money.

If you have a scale check the weight of the powder charge dispensed by the disk combination. Example: If a powder has a VMD of .1064 , and the desired charge weight is 4 grains, 4 x .1064 = .4256, or . 43 cc' The formula for SD is: SD = WG /7000 x D 2. Where WG is weight is in grains and D is is the bullets diameter in inches. Example: For a 180 grain .30 caliber bullet, SD = 180/7000 x .308 squared. Divide the bullets weight in grains (180) by the number of grains in a pound (7000), which yields .2571428

Plaster of Paris is a fine powder and should not be inhaled. Pour material slowly and use a mask if you feel the need. But, it is a safe material with great casting potential. One serious caution is to dispose it as the solid and not put it in a drain as it will clog the pipes Using MB Formula instead will yield the most gold from filings and bench sweeps while providing a brilliant melt. And it eliminates the time-consuming mess of removing hidden gold from borax residue. MB Formula is a powder, and is provided in a jar containing 7.5 ozs. of flux In casting aluminum objects, molten aluminum is poured into a mold. One of the techniques for making an aluminum mold is called sand casting. It involves mixing fine sand, some clay, and a small amount of water to make the mixture cohesive. This mixture is called green sand because it is moist, not because it is.

Slush casting is a variation of permanent mold casting that is used to produce hollow parts. In this method neither the strength of the part nor its internal geometry can be controlled accurately.
