The .277 Wolverine will never replace larger high-power cartridges such as the .308 Winchester (7.62×51mm NATO) or .270 Winchester for long range shooting; however – it outperforms the .223 Remington at typical hunting ranges and approaches the 6.8 SPC while using less expensive components (brass, magazines, bolt, less powder per load).

The 6.5 Grendel bullets have a true diameter of 6.71mm / 0.264" and the 6.5 Grendel case can be formed from ...
That is not to say the round does not have tactical applications as its ballistics exceed that of the 5.56×45mm NATO cartridge. The cartridge name is derived from its caliber (.257 in (6.5 mm) bullet) and case length of 45 millimeters (necked-up 5.56×45 mm), as opposed to older hyphenated cartridges that were named for caliber and powder charge.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load ...
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.65×53mm Mauser, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is ...
The overall case length after the shortening and re-sizing is 1.565". The cartridge was designed to use .308" diameter bullets in weights of 110 to 150 grains, with a standard twist rate of 1-12". [1] Wilson Combat states that heavier bullets can be used in a barrel with a 1-8" twist rate for subsonic loads. [4]
The 6XC is a 1000-yard cartridge, comparable to benchrest calibers such as 6x47mm Swiss Match, 6.5×47mm Lapua and 6 mm/22-250; it fits into cartridge class that exceeds the velocities of benchrest calibers such as 6mm BR Remington, 6mm BRX and 6mm Dasher. David Tubb has claimed several wins with the 6XC in NRA High Power National Championships ...
The .458 SOCOM (11.63×40mmRB) is a moderately large round designed to work in an AR-15 platform.This is achieved by installing a 458 bolt and barrel. The 300-grain (19 g) round offers a supersonic muzzle velocity of 1,900 ft/s (580 m/s) and 2,405 ft⋅lbf (3,261 J), [1] similar to a light .45-70 but with a much smaller case.
