The Hornady Custom-Grade Neck Size Die (6.5mm / .264 Caliber, MPN: 046043) is an indoor bench reloading tool engineered to resize only the case neck of fire-formed bottleneck rifle brass. By leaving the case body and shoulder dimensions fire-formed to the rifle's specific chamber, this die reduces work-hardening of the brass and maintains concentric chamber alignment. It utilizes standard 7/8"-14 threads to mount directly into standard single-stage and progressive reloading presses.

Key Features

• Targeted Neck Sizing: Resizes only the neck of fire-formed cases without disturbing the case body or shoulder geometry, extending brass life and preserving fire-formed chamber fit.
• Zip Spindle™ System: Incorporates a threaded spindle and collet mechanism that permits precise micro-adjustments or quick linear slippage-free repositioning for depriming and alignment.
• Polished Internal Surfaces: Precision-machined, smooth internal geometry eliminates friction to prevent case binding and galling during operation.
• Standard Thread Mounting: Fitted with standard 7/8"-14 die threads to ensure broad compatibility across standard workshop metallic reloading presses.

Who is the Hornady 6.5mm Cal. Neck Sizing Die for?

• Precision rifle competitors shooting bolt-action 6.5mm platforms — Requires sizing only the neck of 6.5mm (.264) calibre bottleneck cases to maintain tight fire-formed chamber alignment and minimize runout, mounting via standard 7/8"-14 press threads with a compact 227 g die footprint.
• Handloaders seeking extended case life for single-rifle brass — Works fire-formed 6.5mm (.264) brass by omitting body and shoulder resizing, extending case cycle life while running on standard 7/8"-14 single-stage or progressive presses weighing approximately 227 g.

Less suitable for: Handloaders processing brass for semi-automatic, pump-action, or lever-action actions, reloaders preparing new, unfired brass or mixed-origin range brass, and cases exhibiting difficult bolt closure after 3 to 5 firings due to chamber stretch; these applications require a standard full-length sizing die or dedicated shoulder-bump die to ensure reliable chambering and feeding.
