History of the 308 AR-10 Ammo
The 308 AR-10 ammo has its roots in the late 1950s when the British military was searching for a new service rifle. The result was the Enfield EM-2 rifle, which used the .280 British cartridge. However, the cartridge was not a commercial success, and the British military eventually adopted the 7.62x51mm NATO cartridge for their service rifle, the L85A1.
Despite the British military’s decision, the .280 British cartridge continued to be used in civilian markets, and it was eventually adopted by the American firearm manufacturer, Ruger. Ruger developed the Ruger Mini-14 rifle, which used the .280 British cartridge. Later, the cartridge was renamed to 308 AR-10 to differentiate it from the .308 Winchester cartridge.
Technical Specifications
Here are the technical specifications of the 308 AR-10 ammo:
Parameter | Value |
---|---|
Caliber | 7.62x51mm |
Case Type | bottlenecked |
Case Capacity | 2.85 inches |
Maximum Bullet Diameter | 0.311 inches |
Maximum Case Length | 2.0 inches |
The 308 AR-10 ammo is a bottlenecked cartridge, which means it has a narrow neck that allows for better bullet fit and accuracy. The case capacity of 2.85 inches is slightly larger than the .308 Winchester cartridge, which contributes to the increased bullet weight and velocity of the 308 AR-10 ammo.
Performance and Ballistics
The 308 AR-10 ammo offers excellent performance and ballistics. The increased bullet weight and velocity of the 308 AR-10 ammo compared to the .308 Winchester cartridge result in improved long-range accuracy and terminal ballistics.
Here are some key performance and ballistics characteristics of the 308 AR-10 ammo:
- Bullet Weight: The 308 AR-10 ammo typically uses bullet weights ranging from 150 to 175 grains. The heavier bullet weight contributes to better long-range performance and increased energy transfer upon impact.
