Hornady 6mm ARC – 103gr ELD-X
A long-range precision hunting load for the modern AR platform.
Developed by Hornady and originally tested by a U.S. Department of Defense unit for a multipurpose combat rifle program, the 6mm ARC (Advanced Rifle Cartridge) was engineered to deliver maximum efficiency and performance in the AR-15 platform. By blending low recoil, high ballistic efficiency, and excellent terminal performance, the 6mm ARC offers a versatile solution for hunters and shooters looking to extend their effective range without stepping into a heavier platform.
The 103gr ELD-X variant is one of Hornady’s most capable hunting loads for the 6mm ARC, designed to deliver deep penetration and controlled expansion on medium-sized game. It’s an ideal option for deer and hog hunting, offering great energy retention and accuracy from ARs and bolt guns alike.

Notes from Ally Munitions
This is a capable hunting load that has performed well on whitetail and hog-sized game out to mid-range distances. The 103gr ELD-X offers great energy retention and expansion on impact, while maintaining excellent accuracy in barrels with twist rates from 1:7" to 1:8". It performs best in longer gas systems, particularly in suppressed setups. While some users may experience mild blowback with traditional suppressors, overall reliability and group consistency have been very solid in our experience.
