Neck tension directly affects pressure curves, velocity consistency, and seating depth precision. Standard dies lock you into one dimension. Generic bushings don’t fit the Cortina system. You’re left guessing or settling for whatever tension the die happens to give you.
These proprietary bushings are built specifically for the Cortina Micro HS FL sizing die. They’re not compatible with standard Hornady or other brand bushings, so don’t try to substitute. Each bushing is machined to exact tolerances, giving you repeatable neck sizing that stays consistent across hundreds of rounds.
Part of the Sherman matched system, these bushings work with Sherman head-stamped brass and the Cortina die body to give you full control over your case prep. Choose the bushing diameter that delivers the neck tension your load needs, whether you’re running heavy match bullets for competition or hunting projectiles that need reliable expansion.
The result is consistent bullet seating, predictable pressure, and better accuracy downrange because your brass prep isn’t fighting against your load development.
Note: These bushings are for Cortina Dies only and will not fit Hornady dies.
