What calibres and loaded brass dimensions is the Redding .198 bushing designed for?

The Model 73198 bushing features an internal sizing diameter of 0.198 inches, making it ideal for precision handloading of .17-caliber cartridges such as .17 Hornet, .17 Remington, and .17 Fireball. It is specifically engineered for case necks measuring approximately .199" to .200" loaded outer diameter, allowing for the standard 0.001" to 0.002" reduction required for proper bullet tension.

Do I need to lubricate case necks when using this heat-treated steel bushing?

Yes, unlike Redding's Titanium Nitride coated alternatives, this standard heat-treated steel bushing requires case neck lubrication prior to sizing to prevent brass galling and ensure smooth operation. The hand-polished internal bore with a surface hardness of Rc 60-62 significantly reduces sizing effort when proper lubrication is applied.

Which dies are compatible with the Redding 73198 sizing bushing?

This bushing has standard outer dimensions of 1/2 inch O.D. and a 3/8 inch length, allowing it to freely interchange across all Redding Bushing-Style Dies including Type S Full Dies, Type S Neck Sizing Dies, and Competition Neck Sizing Dies. It is also fully compatible with standard Wilson-style bushing dies.

Are there any special electrical or regulatory compliance requirements for this product in Australia?

No, the Redding .198 bushing is a purely mechanical, unpowered reloading accessory. Consequently, Australian electrical requirements such as 240V mains, SAA approvals, plug standards, and RCM compliance are completely inapplicable, and the item is fully legal for retail and use across all Australian states and territories.

Neck Sizing Bushing - Redding 73198

The Redding .198 Heat-Treated Steel Neck Sizing Bushing (Model 73198) provides precise control over rifle case neck dimensions and bullet tension without an expander ball. By sizing only the outside diameter of the case neck, this mechanical reloading component reduces brass work-hardening and minimizes concentricity runout. Manufactured from heat-treated steel with a hand-polished interior bore, it delivers smooth sizing operation across standard reloading press setups. Case neck lubrication is required during use.

Key Features

Precise Neck Tension: Sizes the case neck exterior directly, eliminating the need for an expander ball and minimizing case neck runout.
Hardened Steel Construction: Heat-treated steel core rated at Rockwell C (Rc) 60–62 surface hardness for extended operational life and wear resistance.
Polished Interior Bore: Hand-polished internal surface reduces friction and prevents brass galling during the sizing stroke.
Laser-Etched Sizing Mark: Features a clear .198 size designation on the bushing face for rapid identification on the reloading bench.
Broad Die Compatibility: Interchanges freely across all Redding Type S Neck Sizing Dies, Type S Full Length Dies, Competition Neck Sizing Dies, and standard Wilson-style bushing dies.

Who is the Redding .198 Heat-Treated Steel Neck Sizing Bushing for?

Precision small-bore handloaders — requires an exact 0.198-inch internal sizing diameter to achieve consistent neck tension on .17-caliber cartridges such as .17 Hornet, .17 Remington, and .17 Fireball using this steel neck sizing bushing.
Benchrest competitors — benefits from the Rockwell C (Rc) 60–62 surface hardness and precision-machined 1/2-inch (12.7 mm) outside diameter to eliminate expander ball brass distortion and maintain tight concentricity tolerances.

Less suitable for: Reloaders working with loaded cartridge neck diameters exceeding .199" to .200" O.D., who require a larger increment bushing from Redding's sizing line, or operations reducing neck diameter by more than 0.004"–0.005" in a single pass, which require intermediate step-down bushings or body/full-length sizing dies to prevent shoulder collapse.
