They become progressively more inaccurate beyond ranges of 300 to 400 yards. The effects of changing ballistic coefficients (BC) with distance can be modeled with several commercially available ballistic calculators, but it is virtually impossible to know what the actual BC changes are without Doppler radar data. Reducing velocity to measure the simulated BC in mid-flight does not reflect the effects of aerodynamic heating on the tip.

It depends on retained velocity and is therefore cartridge dependent. In general, the ELD-X bullets will provide reliable and effective terminal performance up to velocities of approximately 1,600 feet per second. Click here for more information on Hornady Heat Shield Technology.

No, we are simply providing a bullet that is capable of excellent terminal performance, accuracy and reduced wind drift that is lethal at ranges from near and far. It's our opinion that you should get as close to your quarry as possible. In certain instances, you simply shouldn't take the shot.

The new Heat Shield tipped bullets provide both aeroballistic and terminal performance advantages. The class-leading ballistic coefficients provide flatter trajectories, less wind drift and higher impact velocities. The ELD bullets provide terminal performance far superior to traditional bullet designs over a much wider range of velocities.... Continue Reading

All ballistic coefficients (BCs) were determined using Doppler radar by measuring bullet velocity as a function of distance to ranges of up to one mile. Doppler radar provides velocity measurements roughly every one to two feet of the bullet's flight, resulting in exact measurements of velocity loss due to drag. By using state-of-the-art aeroballistics software (6DOF), large amounts of data can be analyzed and computed to provide extremely accurate determinations of projectile drag.

For match use, many shooters find that one bullet shoots better in their specific rifle than others. BTHP bullets provide another option for match and target shooters to tune loads for the specific application. Click here for more information on Hornady Heat Shield Technology.

Doppler radar testing has shown that tip deformation or melting occurs out to ranges of 500 to 600 yards, depending on the ballistic coefficient. Bullets designed for conventional ranges up to 400 yards, such as the SST, do not have long enough time of flight over these distances to show a significant effect of tip deformation in a...

Every bullet manufacturer's tips begin to melt and deform depending on their specific material properties. In general, standard acetals and Delrins, currently used in bullet tips, begin to soften and deform at 150 to 200 degrees (F). At 250 to 350 degrees (F), they will begin to melt and badly deform. The longer the exposure... Continue Reading

It is a function of the softening point of the plastic, air temperature, ballistic coefficient (BC) and the maximum velocity. Basically, it is how long the bullet tip is exposed to what level of temperature. The higher the muzzle velocity, the higher the maximum temperature on the tip. The higher the BC, the longer the tip is exposed to... Continue Reading

High-velocity impacts may occasionally cause the ELD-X bullet jacket to roll back past the InterLock ring during penetration, leading to jacket core separation as the bullet comes to rest. When bullets stop inside an animal, the elasticity of the flesh, and especially the hide, pulls the bullet backward into the animal and often flips... Continue Reading
