May 25th 2023Whoever dies with the greatest number of toys wins, right? Sinclair has a new gadget that you can add to the reloading bench. The Sinclair Case Neck sorting tool allows you to quickly sort brass according to the thickness of the neck-wall. This tool can help improve neck tension consistency for those who shoot “no turn” brass. Inconsistent neck “grip” can be caused by large variations in neck-wall thickness. We’ve found, in general, that a more consistent neck tension lowers ES and improves accuracy. We know of some guys who shoot 6mmBR no-turn brass with great success in competition — but their secret lies in pre-sorting the brass by neck wall thickness. Cases that are not within spec are either skim-turned or set aside for sighters. How the Case Neck Sorting tool WorksHere’s a video showing how the Sinclair tool operates. The tool rotates the cases under an indicator tip, while they are supported by a case-neck driver and a support pin that passes through the flashhole. The unit is stable due to its wide base and low profile. The tool is designed to work with.22-.45-caliber cartridges, but can also be used for.17-.20-caliber cartridges when using the optional carbide aligning rod. The MIC-4 pin is compatible with both.060 flash holes (PPC size), and.080 standard size. Sinclair’s Case Neck Sorting tool can be ordered either with or without dial indicator. The basic unit (item 749006612), without dial indicator, is priced at $59.99. The tool with dial indicator is available for $89.99. This sorting tool needs caliber-specific case neck pilots, which must be purchased separately. Editor’s Commentary: The purpose of the Sinclair tool is to quickly sort large quantities of cartridge brass in order to determine significant variations in case-neck-wall thickening. Consider this tool a rapid culling/sorting device. If you are turning necks, a quality ball-micrometer tool is still needed to measure the neck-wall thickness before and after neck-turning.
