Superformance® - It IS rocket science!®

Hornady has been on the cutting edge of ammunition technology for over six decades. Each year our engineers strive to introduce even more revolutionary products. In 2010, their tireless pursuit of excellence brought us the technology behind Superformance ammunition. By blending propellants and manipulating burn rates, we have been able to obtain velocities that were never before attainable in conventional centerfire rifle cartridges.

This year we have tailored a line of ammunition in response to the demands of the global hunter. In keeping with our tradition of innovation, we have introduced Superformance International ammunition. Loaded with the latest GMX bullets and chambered in the most popular European calibers, Superformance International is the new Gold Standard for your rifle.
