About the Manufacturer
"Ten bullets through one hole" was the philosophy of Joyce Hornady, the company's founder. This great idea of accuracy and perfection has continued from the first bullet made more than sixty years ago, right through today. Like so many successful companies, Hornady Manufacturing was born out of one man's vision of a better product for his own use. Joyce Hornady was an avid shooter and needed a steady supply of good, accurate bullets. While commercially available bullets were usable, Joyce felt that better bullets could be made. We continue to be one of the largest independent producers of bullets in the World. They sell bullets as separate components, loaded in Hornady Ammunition, and also to other ammunition companies to be loaded in their premium grade ammo. Their employees exhibit our products at trade shows and shooting matches across the country, and our product lines are represented to dealers and distributors by over 70 independent sales representatives. Hornady Manufacturing has been the recipient of many industry awards and has also given generously within the community of Grand Island, where we make our home. Organizations supported include the United Way, the Platte River Charity Shoot, the Heartland Public Shooting Park, Hope Harbor, the Central-Plains Chapter of the American Red Cross, Stuhr Museum and the list goes on. Hornady was the leading founder of the Hunting and Shooting Sports Heritage Fund, and they support or serve on The National Shooting Sports Foundation, Honored American Veterans Afield, the Sporting Arms and Ammunition Manufacturers Institute, The National Rifle Association, and many others. As a member of the shooting and hunting sports industry, Hornady realizes the need to give back to the sports that keep them in business and maintain our heritage..  The stature of Hornady Manufacturing Company within its industry has never been higher. Combine the best customer base with the best employees, throw in the family/management team running this business; it's hard not to be successful.

About the 7.62x39mm
The 7.62×39mm (aka 7.62 Soviet) round is a rimless bottlenecked intermediate cartridge of Soviet origin that was designed during World War II. Due to the worldwide proliferation of RPD and RPK light machine guns and SKS and AK-47 pattern rifles, the cartridge is used by both militaries and civilians alike. 7.62×39mm ammunition is purportedly tested to function well in temperatures ranging from −50 to 50 °C (−58 to 122 °F) cementing its usefulness in cold polar or hot desert conditions. The 7.62×39mm cartridge was influenced by a variety of foreign developments, including the German Mkb 42(H) and the U.S. M1 carbine. Shortly after World War II, the world's most widespread military-pattern rifle was designed for this cartridge: the AK-47. The cartridge remained the Soviet standard until the 1970s. It was largely replaced in Russian service by the 5.45×39mm cartridge, which is used by the current-issue AK-74M service rifle and its variants. In the 21st century the 7.62×39mm remains a common service rifle chambering, including for newly developed rifles.
