DRVT — DRAG VARIABILITY REDUCTION TECHNOLOGY
Using Doppler radar and Schlieren imagery, Hornady engineers have developed and patented Drag Variability Reduction Technology (DVRT) to increase the uniformity of bullet drag from shot to shot, resulting in less dispersion at long range.

While analyzing thousands of Doppler radar drag curves, Hornady’s ballisticians isolated a bullet tip design that would reduce the variation in drag from bullet to bullet. Specifically, the meplat must be flat – not pointed – and the diameter of the flat meplat is a specific ratio to the bullet diameter. Tests showed that a flat end of the bullet tip provided more consistent drag.

Introducing DVRT™ – Drag Variability Reduction Technology from Hornady Manufacturing.

Upon refinement of this design feature in late 2018, DVRT was implemented into all bullets using the Heat Shield Tip and the A-Tip Match bullet. While DVRT was patent pending, shooters quietly benefited from this design for several years. Now with the patent issued, Hornday has published the details of Drag Variability Reduction Technology on its website. And the hour-long Hornady Podcast embedded below explains how DVRT was developed from extensive field research with Doppler radar.
