Category: Projectiles (Reloading Components)
Hornady’s .338 307 gr Sub-X bullets are built for hunters and precision shooters who want serious terminal performance without the sonic crack. Purpose-designed for subsonic loads, these heavy-for-calibre projectiles pair a lead core with a gilding metal jacket, patented Flex Tip insert and deep grooves to guarantee reliable expansion and penetration at low velocities – right down to around 900 fps. The cannelured jacket gives you a solid, positive case crimp, making them ideal for semi-auto rifles and tubular magazines where feed reliability is non‑negotiable.
In the field, the 307 grain weight and sleek profile deliver excellent stability and accuracy, especially in modern cartridges like the .338 ARC and other subsonic .338 setups. They’re tuned for medium game in the 50–300 lb bracket, giving you clean kills and controlled expansion while keeping noise and recoil down – perfect for suppressed rigs and close‑range work around properties or in tight bush. If you’re chasing a dependable subsonic .338 bullet that hits hard, groups tight and plays nicely with gas guns, this 50‑pack of Hornady Sub‑X is ready to slot straight into your next load development session.
Key Features
- Subsonic expanding design delivers reliable expansion at low velocities, making it ideal for quiet, subsonic hunting and shooting applications.
- Patented Flex Tip® polymer insert aids expansion down to approximately 900 fps, helping the bullet open up and transfer energy even at reduced speeds.
- Heavy 307-grain weight and .375 (G1) ballistic coefficient provide excellent stability and predictable trajectory for medium game within typical subsonic ranges.
- Lead core with gilding metal jacket and cannelure allows a secure case crimp, improving feeding reliability in semiautomatic and gas system rifles.
- InterLock® ring mechanically locks the core and jacket together to promote deep penetration and controlled expansion on game animals.
- .338 calibre (.338" diameter) Sub-X® profile is engineered to fit, feed and function smoothly in a wide variety of rifles chambered for compatible .338 cartridges, including .338 ARC.
- Meets FBI protocol for terminal ballistic test requirements, giving shooters confidence in consistent performance on critical shots.
- Recommended minimum 1:8" twist rate ensures proper stabilisation of the long, heavy bullet for tight groups and dependable accuracy.
- Optimised for medium game in the 50–300 lb class, offering a purpose-built solution for pigs, goats and similar-sized animals.
- Supplied in a 50-count box, providing enough projectiles for load development and extended practice sessions without frequent resupply.
