Whidden 308 Win Length Bushing Sizer & Micrometer Seater Die Set

The Whidden Bushing Sizer Die allows the flexibility of neck tension should a different thickness in the neck of the brass occur from one manufacturer to another. The bushings also allow the shooter the opportunity to achieve the desired neck tension after neck turning of the brass. The bushings allow for .001” increments in neck tension in a range from .17 to .338 calibers.

For precise, consistent OAL handloads, the internals of Whidden’s sizing die are designed to keep your rounds …. Round. Whidden’s hand-polished sizer die has a shorter OAL for better shoulder bump-back, a smaller base, and tighter internal tolerances.

The micrometer adjustable seating die has flutes for precise hand adjustment at the loading bench. The depth increments are easily read and will stay that way for years of use. Inside the die a sliding sleeve system helps to improve concentricity – a must for repeatable precision.

Includes: Whidden Shoulder Bump Gauge
