The 115 gr (7.5 g) 6.8-round has a higher muzzle energy of 1,694 ft⋅lb (2,297 J) due to its greater velocity, while the 125 gr (8.1 g) 300 BLK round has a muzzle energy of 1,360 ft⋅lb (1,840 J). Both rounds were made to be used in an easily converted AR-15 .
This round has the same overall length and width as the popular 5.56×45mm NATO round, except it fires a 30 caliber bullet allowing for better barrier penetration and external ballistics from short barrels. These dimensions allow the 300 AAC Blackout to be used in existing magazines designed for M16 or AR-15 rifles. Because the rim of the ...
Combined with the poorer ballistic coefficients of the lighter projectiles (.267 for the 125-grain Core-Lokt), this makes the .30 RAR a cartridge suited to ranges around 300 to 400 yards, although this can be extended with projectiles of higher ballistic coefficient (.341 for the Speer TNT 125 grain).

Previous reporting by the Star-Telegram shows the silos and grain elevator date to 1924, when Fort Worth was considered the grain capital of the Southwest, according to an archivist at the Fort ...
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
M1: This was used by seacoast artillery for major-caliber seacoast guns. It computed continuous firing data for a battery of two guns that were separated by not more than 1,000 feet (300 m). It utilised the same type of input data furnished by a range section with the then-current (1940) types of position-finding and fire-control equipment.
