Hornady 30 Cal .308 178gr ELD-X Component Bullets
The Hornady ELD-X (Extremely Low Drag – eXpanding) in .308″ diameter, 178 grains is a component projectile for handloaders who want a single hunting bullet that performs reliably from close-range woodland shots out to extended distances. The Heat Shield tip is immune to aerodynamic heating during flight, so the ballistic coefficient — verified by Doppler radar — remains consistent across the full trajectory. At conventional ranges (0–400 yards), the high-velocity impact causes the bullet to expand progressively, with the thick jacket shank and InterLock ring keeping core and jacket together for around 50–60% weight retention and deep penetration. At extended ranges beyond 400 yards, where velocity has dropped, the Heat Shield tip drives rearward into the hollow-point cavity to reliably expand and maintain terminal performance.

FAQ
What makes the Heat Shield tip different from standard bullets?
The Heat Shield tip resists aerodynamic heating during flight, maintaining a consistent ballistic coefficient across the trajectory, which improves accuracy and performance at extended ranges.
How does the bullet perform at extended ranges beyond 400 yards?
At extended ranges beyond 400 yards, the Heat Shield tip drives rearward into the hollow-point cavity to ensure reliable expansion and penetration despite reduced velocity.
Is this bullet suitable for handloading?
Yes, this is a component bullet specifically designed for handloaders who want a reliable, high-performance hunting round with consistent expansion and penetration.



Michael Lawrence –
Used this bullet for a recent woodland hunt and was impressed with the consistent expansion at 300 yards. The bullet retained most of its weight and penetrated deeply. Good for close to medium range shots.
Zoe Duncan –
Felt more reliable than other component bullets I’ve tried. The expansion was predictable and the bullet didn’t fragment early. Works well in my .308 rifle at typical hunting distances.
Dylan Rees –
The Heat Shield tip performed well even at 450 yards. The bullet expanded properly and maintained integrity. Great for long-range hunting in dense cover.
