Will these .323 diameter bullets work safely in my older historical 8mm rifle?

These Hornady 170 grain SST bullets feature a true .323 inch diameter and are designed for modern .323-bore rifles such as the 8x57mm IS, 8mm Remington Magnum, and .325 WSM. They are strictly incompatible with older .318-bore 8mm rifles, such as original .318 inch 8x57 I-bore barrels, which can cause dangerous over-pressure if fired.

How does the polymer tip and InterLock ring perform on medium to large Australian game?

The polymer tip acts as a wedge to initiate rapid, controlled expansion upon impact while delivering a flat trajectory with a G1 ballistic coefficient of 0.445. Additionally, the integrated InterLock ring mechanically locks the tapered copper jacket to the lead core, ensuring reliable weight retention when taking species like fallow deer, sambar deer, or feral pigs.

Are there any specific reloading dies and accessories you recommend for setting up these 8mm bullets?

For precise handloading, you can pair these components with standard 8mm reloading setups along with tools like the Hornady Custom Grade New Dimension Dies and the Hornady Powder Cop Reloading Die to monitor powder charges accurately. To streamline your press setup during batch reloading, integrating Hornady Lock-N-Load Quick Change Die Bushings will also allow you to swap dies instantly without losing your adjustments.

Do I need any electrical certifications or special permits to purchase and store these reloading components in Australia?

No electrical certifications like SAA or 240V ratings apply, as these are passive metallic projectiles containing no active electronics, primers, or propellants. While unprimed reloading projectiles are generally unrestricted compared to loaded ammunition, you must always ensure your finished handloads comply with state and territory firearms laws, including minimum calibre and energy thresholds for deer hunting set by authorities such as the Victorian Game Management Authority.

8mm Reloading Bullets - Hornady 3233

The Hornady 8mm .323 170 gr SST (Super Shock Tip) is a component projectile engineered for handloaders targeting medium to large game. Featuring a polymer tip, Hornady secant ogive, and boat-tail base, this 170-grain bullet delivers a flat trajectory and rapid, controlled terminal expansion. An internal InterLock ring mechanically locks the lead core to the tapered copper jacket, ensuring core-jacket integrity and weight retention upon impact. Each box contains 100 unprimed component bullets designed for reloading .323-calibre centre-fire cartridges.

Key Features

Polymer Tip Design: Enhances in-flight aerodynamics and acts as a mechanical wedge upon target impact to initiate reliable, rapid expansion.
Secant Ogive and Boat-Tail Profile: Minimises in-flight drag to generate a 0.445 G1 ballistic coefficient for flatter shooting at extended ranges.

Who is the Hornady 8mm 170 Grain SST Bullets 100 Pack for?

Australian medium to large game hunters — requires a 170-grain .323-calibre reloading bullet that delivers immediate shock and rapid expansion for game between 23 kg and 680 kg, including feral pigs, goats, fallow deer, and sambar deer.
Bespoke 8mm centre-fire handloaders — leverages a 0.445 G1 ballistic coefficient and a 0.233 sectional density to load flat-shooting ammunition into modern .323-inch chambers such as 8x57mm IS, .325 WSM, and 8mm Remington Magnum.

Less suitable for: Firearms with historical .318-inch groove diameters (such as early 8x57 I-bore rifles), which require dedicated .318-bore projectiles; or point-blank, high-velocity magnum impacts into heavy bone, where bonded-core or monolithic copper bullets are better suited to prevent jacket fragmentation.
