ELD® Match (Extremely Low Drag Match) bullets are technologically advanced, enhanced accuracy target bullets featuring Heat Shield® tips with the PERFECT MEPLAT (tip point) combined with numerous design features that deliver the highest-in-class ballistic coefficients, superior accuracy and extreme consistency from bullet to bullet, lot to lot.
Superior accuracy and industry leading ballistic design has been achieved with the ELD Match bullet. An optimum secant ogive and boattail design along with the Heat Shield tip produce a bullet with the highest possible ballistic coefficient in its class.
- Best-in-class BCs
- The Heat Shield® tip is immune to the effects of aerodynamic heating and retains its shape to provide a perfect meplat (tip) that is always the same shape.
- Delivers the highest degree of accuracy and consistency
- Streamlined secant ogive with optimum boattail design + highly concentric AMP® bullet jackets + Heat Shield® tip creates a supremely accurate, high BC match bullet.
- Accurate, Doppler radar verified BCs
- ELD® Match bullet BCs are measured with Doppler radar and corrected to standard atmospheric conditions.
- The Perfect Tip
- The new Heat Shield® tip creates the perfect meplat and outperforms BTHP bullets.

ELD® Match Expanded Ballistic Coefficient Values:
Hornady originally published “800 yard”* average Ballistic Coefficient (BC) values for ELD-X and ELD Match bullets. This was done to provide the most usable BC from a trajectory prediction standpoint. Unfortunately, many shooters did not understand that Hornady was listing a more useable “800 yard” BC while other manufacturers list “200 yard”* BCs. When doing pre-purchase research either on the web or at the store, the increased performance of the ELD Match and ELD-X bullets wasn’t always realized in a head-to-head BC comparison.
Newly Published base of comparison
Hornady now publishes “200 yard” Mach 2.25 (2,512 fps @ ICAO Standard Atmosphere**) G1 and G7 Ballistic Coefficient (BC) numbers for all A-TIP, ELD-X, and ELD Match bullets. Mach 2.0 (2,233 fps @ ICAO Standard Atmosphere) and Mach 1.75 (1,954 fps @ ICAO Standard Atmosphere) BC values are also available.
As Hornady moves the industry to drag coefficient based trajectory calculations for these types of projectiles, the Ballistic Coefficient is becoming somewhat irrelevant. Exceptions are for those still using BC based trajectory calculators or when using BC as rating criteria for bullet performance.
Ballistic Coefficient (BC) values at Mach 2.25 (2512 fps @ ICAO Standard Atmosphere) should be used when comparing to other published BC values within the industry. Ballistic Coefficient values at Mach 1.75 (1954 fps @ ICAO Standard Atmosphere), should be used when calculating trajectories for shooting beyond 600 yds. Ballistic Coefficient values at Mach 2.0 and 1.75 offer comparisons to other manufacturers that publish multiple BC’s based on velocity.
A Positive Gain
In addition to the change listed above, a select few ELD-X and ELD Match bullets initially had BC values that were determined from prototype bullets. As Hornady moved into production of these bullets, the BC value increased (a positive gain) due to the improvements in the manufacturing process from R&D to production machinery.
The Science Behind It
Ballistic Coefficient (BC) values can, and usually do change in value with changes in velocity. Most bullets exhibit a lowering BC as velocity slows. The extent of how much a BC will change depends on each unique bullet shape. When comparing BCs of different bullets, it is important to use an apples-to-apples approach.
To do this, bullets should be compared at a given Mach number (e.g. Mach 1 = 1116.48 fps @ ICAO Standard Atmosphere). Mach number is the velocity of the bullet divided by the speed of sound. If a Mach number is unavailable, velocity can be used if the BCs are corrected to Standard Atmosphere which is fairly typical practice within the industry.
The majority of industry published BCs is measured over relatively short ranges of 100 to 300 yards, which corresponds to velocities around 2500 fps depending on muzzle velocities. Some manufacturers offer BC values at different velocity ranges.
- Mach 2.25 (2512 fps* and above) – Velocities above 2,500 fps and distances out to 300 yards.
- Mach 2.0 (2232 fps*) – Mid-range shooting where the bullet spends time in flight after slowing down.
- Mach 1.75 (1953 fps*) – Long-range shooting where much of the bullet flight occurs after velocity loss.
