These die sets feature a Full Length Sizer die that uses precision-machined neck bushings (sold separately) to size the case neck just enough provide the exact amount of bullet tension without overworking the brass. To determine the proper neck bushing size, measure the outside neck diameter of a loaded cartridge and subtract .002" to .003" to allow for a small amount of brass spring back. The Gold Medal Seater Die features a micrometer adjustment knob so that bullet depth can be precisely set and reset. The micrometer is connected to a free floating and self centering bullet seating system and has a convenient bullet loading window for easy loading. Shellholder sold separately.

To determine bushing size, measure the outside neck diameter of a loaded cartridge, subtract .002" to .003" -- this allows approximately .001" of brass spring back for correct neck tension. Another method is to measure the neck wall thickness of a case, multiply by two, add the diameter of the bullet and subtract .001" -- RCBS suggests purchasing neck bushings one to two sizes above and below the target diameter.
Gold Medal seating dies have a micormeter adjustable, free floating and self-centering bullet seating system with a bullet loading window.
