The case head diameter of the Grendel is the same as that of the 5.6×39mm (.220 Russian), 7.62×39mm and 6.5mm PPC cases. This diameter is larger than the 5.56×45mm NATO, thereby necessitating the use of a non-standard AR-15 bolt. The increased case diameter results in a small reduction in the magazine ammo capacities.
The 6mm Creedmoor is a necked-down version of the 6.5mm Creedmoor using 6 mm (.243 inch) bullets, lighter than 6.5 mm bullets with similarly reduced recoil. [30] John Snow at Outdoor Life built a 6mm Creedmoor rifle in 2009 for a magazine article of the wildcat cartridge that appeared in 2010, but the first documented conception of the 6mm ...

6.5mm Creedmoor, 6.5×48 mm, introduced in 2007; 6.5×47mm Lapua, a 2005 cartridge that fires the same diameter and weight 9.0g bullet as the 6.5×54mm but achieves a faster muzzle velocity; 6.5×53mmR, the rimmed Romanian and Dutch service rifle cartridge from the 1890s through World War II
Thanks in part to its relatively roomy case which was designed for loading long, heavy 6.71 mm (0.264 in) bullets, and a 12.2 mm (0.480 in) diameter bolt face, it has proven more successful than other first-generation smokeless-powder military cartridges of similar bullet calibers, such as the 6×60mm US Navy, 6.5×54mm Mannlicher–Schönauer ...
