What calibres and bullet sizes is the Hornady 044145 seating die designed to handle?

This die is built exclusively for straight-wall revolver and lever-action cartridges in the .38/.357 family, specifically .38 Special, .357 Magnum, and .357 Remington Maximum using standard .357" nominal diameter bullets. It is not compatible with larger revolver calibres like .44 or .45, nor is it suitable for bottleneck rifle cases.

Does this reloading die require any specific press threads or shell holders to mount on my bench?

The die features an industry-standard 7/8"-14 thread pitch, meaning it will mount directly to any standard single-stage, turret, or progressive reloading press with compatible threads. You will also need to separately acquire a Hornady #6 Shell Holder or Shell Plate to securely hold the cartridge cases during the seating and crimping process.

Do I need a firearms licence to purchase this Hornady seating die in Australia?

No, reloading dies are classified as non-regulated accessory tooling under Australian state and territory legislation, so you do not need a firearms licence or permit simply to purchase or import this tool. However, anyone handling finished ammunition components such as primers, propellants, and projectiles must hold the appropriate state firearms licence.

How does the floating bullet alignment sleeve prevent bullet damage during seating?

The Hornady New Dimension sliding alignment sleeve captures both the case neck and the projectile before the seating stroke begins, holding them in strict coaxial alignment. This mechanical design eliminates bullet runout and prevents the edge of the case mouth from shaving lead or jacket material off the projectile.

38 Cal Seating Die - Hornady 044145

The Hornady Custom Grade New Dimension (CGND) Seating Die (MPN: 044145) is a precision-machined, heat-treated steel metallic cartridge reloading tool designed for .38 Special, .357 Magnum, and .357 Remington Maximum cartridges. Built to handle standard .357" nominal bullet diameters, this die seats projectiles to a consistent overall length and features an internal roll-crimping shoulder to secure bullets in straight-wall revolver brass. It operates via standard mechanical reloading presses utilizing an industry-standard 7/8"-14 thread interface.

Key Features

Floating Bullet Alignment Sleeve: Pre-aligns the case neck and projectile coaxially before seating begins, eliminating runout, shaving, and alignment tilt.
Integrated Roll Crimper: Allows handloaders to seat and roll-crimp in a single stroke, or back off the die body to seat bullets without crimping.
Sure-Loc™ Lock Ring: Clamps around the 7/8"-14 die threads to maintain lock settings without causing thread surface damage.
Compression Lock O-Ring: Applies constant friction to the adjustment screw to prevent thread drift during repetitive cycling while allowing smooth adjustments.
Mechanical Durability: Constructed from heat-treated, polished steel weighing approximately 0.20 kg to 0.25 kg for high-volume handloading operations.
