What is the recommended maximum velocity for the Hornady 10508 158 grain LRN bullets to prevent barrel leading?

These cold-swaged lead bullets are engineered for low-to-moderate velocity applications between 700 and 850 fps in .38 Special loads. Pushing velocity past 900 to 1,000 fps will cause excessive barrel leading and severe accuracy degradation. For full-power loads exceeding these thresholds, you should use jacketed or polymer-coated projectiles.

Can I use these .358 diameter bullets in my modern 9mm pistol or are they strictly for .38 Special?

These bullets feature a nominal diameter of 0.358 inches and are intended for .38 Special, .38 S&W Special, and target-loaded .357 Magnum revolvers or lever-action carbines. They are unsuitable for modern 9x19mm Parabellum bores, which typically measure 0.355 inches.

Do I need any special licensing to purchase these reloading bullets in Australia?

Yes, while these projectiles are unprimed inert components and do not require electrical compliance or SAA/RCM certification, their purchase and possession remain strictly governed by state and territory firearms legislation. Buyers typically need to hold a valid Australian Firearms Licence corresponding to category A, B, or H depending on their jurisdiction.

How many bullets come in a box, and what lubrication feature helps reduce fouling?

Each box contains 300 bullets, with each projectile weighing 158 grains and featuring a ballistic coefficient of 0.159. They incorporate Hornady's exclusive knurled bearing surface system, which holds pre-applied lubricant to effectively minimize bore fouling during high-volume range practice and Cowboy Action matches.

.38 Cal Lead Bullets - Hornady 10508

The Hornady .358 38 Cal 158 Grain LRN Lead Bullets provide handloaders with cold-swaged lead round nose projectiles designed for standard-pressure, low-to-moderate velocity revolver and lever-action rifle loads. Swaged from a solid lead alloy rather than cast, each bullet delivers uniform weight distribution and consistent core density across production runs. The bearing surface features a knurled micro-groove system that holds lubricant directly against the driving bands to minimise bore fouling and prevent barrel leading at conventional target velocities between 700 fps and 850 fps. Compatible primarily with .38 Special, .38 S&W Special, and reduced-velocity .357 Magnum brass, these projectiles offer an economical solution for volume target practice, steel shooting, and SASS-regulated matches within 7 to 50 metres.

Key Features:

Cold-Swaged Lead Construction: Formed under uniform pressure to eliminate internal air pockets and maintain consistent balance and dimensional tolerances.
Knurled Lubricant System: Micro-grooved bearing surface retains pre-applied lubricant to reduce metal-on-metal friction and barrel leading.
SASS Match Ready: Engineered to meet Single Action Shooting Society competitive criteria for Cowboy Action shooting disciplines.
Reliable Chambering: Traditional round nose profile promotes smooth feeding through tubular magazines and revolver cylinders.

Who is the Hornady .358 38 Cal 158 Grain Lrn Lead Bullets 300 Pack for?

Cowboy Action Shooting competitors — requires SASS-compliant plain-base lead bullets engineered for low-recoil .38 Special loads, utilising a 158 gr round nose profile with a 0.159 G1 ballistic coefficient for predictable impacts on close-range steel targets between 7 and 50 metres.
Target handloaders seeking volume range practice — needs consistent, economical reloading lead bullets supplied in a 300 pack, featuring a precise 0.358 in diameter and a knurled, pre-lubricated bearing surface designed to eliminate leading in standard-pressure revolver chambers and lever-action carbines.

Less suitable for: Load recipes designed to exceed 900 to 1,000 fps (such as full-power .357 Magnum cartridges) or firearms featuring modern 9x19mm Parabellum bores typically measuring 0.355 in; high-velocity loads exceeding this limit require gas-checked, polymer-coated, or fully jacketed bullets to prevent severe bore fouling and accuracy loss.
