HORNADY 25 CAL .257 128 GR ELD-X (1-7.5") 100 COUNT

If you're handloading for .25 caliber rifles and demand a bullet that performs across the full spectrum of hunting ranges, the Hornady 25 Cal .257 128 Grain ELD-X is engineered to deliver. Built on Hornady's Extremely Low Drag (ELD-X) platform, this expanding hunting bullet combines match-grade accuracy with terminal performance that works whether your shot breaks at close range or stretches past 400 yards. The 1-7.5" twist rate marking indicates the rifling twist it's optimized for; this matters when you're trying to dial in a load that groups tight and shoots true.

What sets the ELD-X apart is its Heat Shield tip—a polymer design verified by Doppler radar to maintain its shape and resist aerodynamic heating throughout the bullet's flight. That means the advertised ballistic coefficient stays consistent from the muzzle to impact, no degradation in flight. The secant ogive and optimized boattail geometry work together with highly concentric AMP jackets to deliver the aerodynamic efficiency serious long-range handloaders expect. Whether you're preparing ammo for a varmint rifle or a big-game setup, the design lets you trust your velocity predictions and trajectory calculations.

On game, the ELD-X behaves like two different bullets depending on impact velocity. At high velocity (0–400 yards), it expands progressively through the wound channel while the thick jacket shank and InterLock ring keep core and jacket bonded—you'll see 50–60% weight retention and solid penetration. When impact velocity drops at extended range (400+ yards), the Heat Shield tip drives backward to initiate expansion reliably even at lower speeds, resulting in 85–90% weight retention, a wide mushroom, and deep penetration for large wound cavities. This is purpose-built ammunition component engineering: one bullet, two terminal strategies.

You get 100 bullets per box, ready to seat into your reloading dies. If you're working up precision loads for hunting or long-range target work, the ELD-X's match-accuracy heritage and proven field performance make it a natural choice for handloaders who refuse to compromise.

Frequently Asked Questions

What rifle twist rate do these bullets need?

The ELD-X 128 grain .257 is optimized for a 1-7.5" twist. Check your rifle's specs to confirm it falls within or faster than this rate; a twist that's too slow may cause accuracy issues or bullet instability.

Will these expand reliably at long range?

Yes. The Heat Shield tip is designed to drive backward into the bullet at low-velocity impacts (400+ yards), initiating expansion even when impact speeds drop. You'll see 85–90% weight retention and deep penetration at extended range, making it a true all-range hunting bullet.

What weight retention should I expect?

At high velocity and close-to-medium range (0–400 yards), expect 50–60% weight retention. At extended range where impact velocity is lower (400+ yards), you'll get 85–90% weight retention as the Heat Shield mechanism kicks in. Both scenarios deliver sufficient penetration and wound cavity for hunting.

Can I load these for target shooting as well as hunting?

Absolutely. The ELD-X is a match-accurate bullet built on proven aerodynamic design, so it will shoot tight groups on the range. That said, it's engineered and priced as a hunting round, so dedicated target shooters might explore other options depending on volume and budget.
