Description

A comprehensive three-piece lot of RCBS precision reloading equipment tailored for the high-velocity .220 Swift cartridge. This collection includes the essential components for advanced case preparation and sizing. The lot comprises the RCBS F L (Full Length) Die Set (P/N: 10701), the RCBS Neck Sizer Die (P/N: 10730), and the RCBS PRECISION MIC (P/N: 88301). The die sets are marked Group A and require Shell Holder #11. The Precision Mic set, designed for measuring case headspace and bullet seating depth, includes machined black and silver metal micrometer components and a hex wrench, accompanied by an instruction booklet citing U.S. Patent No. 4,918,825 (1990). The Full Length Die Set includes the Sizer Die and Seater Die, while the Neck Sizer contains a single die, both accompanied by instructional materials and small yellow plastic components. All items are housed in their original, bright green hinged plastic cases. The presence of the OMARK INDUSTRIES marking on one case indicates production during or immediately following the period when RCBS was owned by Omark (1976-1985), though the Precision Mic design incorporates later patented technology, placing the overall set in the late 1980s to early 1990s manufacturing window.
