The person who dies with the greatest number of toys wins. Sinclair also has a new gadget that you can add to the reloading bench. Sinclair Case Neck Sorting Tools allows you to quickly sort brass by neck wall thickness. This tool can help improve neck-tension consistency for shooters of “no-turn” brass. Variations in neck-wall thickness can lead to inconsistent neck grip on the bullet. We have found that consistent neck tension can reduce ES and (usually), improve accuracy. Some competitors shoot 6mmBR brass with no-turn and have great success. Their secret is pre-sorting their brass according to neck-wall thickness. Cases that are not in-spec are saved for sighters, or are later skim-turned.
How the Sinclair Tool Works The case neck sorting tool works by rotating the cases under an indicator tip. They are supported on a caseneck pilot and a support pin through a flash hole. It has a wide base and a low profile to ensure it is stable when in use. The tool can be used with.22-.45 caliber cases, and can also be used with.17- or.20-caliber case using the optional carbide alignment rod. The MIC-4 pin can be used with flash holes of.060 (PPC) or.080(standard size). Sinclair’s Case Neck Sorting tool can be ordered with or sans a dial indicator. The basic unit, without a dial indicator (item 759)006-612WB), is $59.99. The tool can also be purchased with a dial indicator (item749-007-12WB) for $89.99. Important: This sorting tool requires caliber specific Case Neck Pilots, which must be ordered separately.
Editor’s comment: This Sinclair tool is designed to quickly sort cartridge brass in high quantities, and determine significant variations in case-neck-wall thickness. This tool can be used as a culling/sorting tool. To measure the thickness of your neck walls before and after turning your necks, you’ll still need a quality micrometer tool.
