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.
