AKA 6.5x39mm

1.508 - 1.512 O.A.L.

The 6.5 Grendel was designed for use in an AR-15 type rifle to offer ballistics similar to the .308 Winchester, with less recoil. This flat shooting round utilizes the inherently accurate, high ballistic coefficient 6.5mm diameter bullet.

Its short case length allows it to use some of the longer, heavier match bullets, making this calibre one of the best choices for long range shooting out of an AR. With proper bullet selection, this calibre is no slouch in the field either, being suitable for deer-size game as well as varmint hunting.

Conversion of an AR to 6.5 Grendel requires a new bolt, barrel and magazines to feed the larger diameter cartridge. Several companies offer complete AR uppers and firearms, and reloading dies are readily available.

Several manufacturers are now producing bolt action rifles in this calibre, many of which are built on "mini" actions, making for a lightweight rifle with plenty of range.
