Kalibrierring aus Stahl für die Gold Medal und Match Master Hülsenhalskalibriermatrizen. Empehlung von RCBS für die Bestimmung des richtigen Durchmessers: Proper neck bushing size can be determined two ways: Measure the outside neck diameter of the loaded cartridge, subtract .002-inch to .003-inch. This allows approximately .001-inch of brass to spring back for correct neck tension. OR Measure the neck wall thickness of the case, multiply by 2, add the diameter of the bullet and subtract .001-inch. RCBS suggests that reloaders have neck bushings one to two sizes above and below their target diameter.
