|Introduced in 2003, the 6.5 Grendel was the result of years of development and testing by
Alexander Arms to produce an intermediate size cartridge for the military M1 or AR-15 rifle to
deliver performance meeting or exceeding the 7.62 NATO (.308 Winchester) and do so with
Due to the superior ballistics of 6.5mm projectiles and the high efficiency cartridge design, the 6.5 Grendel improves upon 7.62 NATO military loadings with better energy at ranges in excess of 400 meters.
The 6.5 Grendel started off as a wildcat cartridge by blowing out the shoulder and necking down
the 7.62x39 Russian to except 6.5 diameter projectiles. However now that factory ammunition is being produced, it should be consider a proprietary cartridge.
