Description

This precision reloading tool is a double-cavity bullet mold manufactured by RCBS under Omark Industries. The mold block is constructed of dark machined metal and is designed to cast .30 caliber, 180-grain semi-pointed bullets. The block is stamped with the manufacturer name RCBS and the model designation 30-180-SP. It includes the original green textured plastic storage box with a factory adhesive label identifying it as Part No. 82020. The label provides technical specifications, recommending the use of a .308 sizer die and a #541 top punch. This item dates to the period after Omark Industries acquired RCBS in 1976 and before the mid-1980s. Dimensions are not available as no scale was provided in the reference images.
