Maximum point-blank range is principally a function of a cartridge's external ballistics and target size: high-velocity rounds have long point-blank ranges, while slow rounds have much shorter point-blank ranges. Target size determines how far above and below the line of sight a projectile's trajectory may deviate.
The .223 Remington (designated 223 Remington by SAAMI [4] and 223 Rem. by the C.I.P. [5], pronounced "two-twenty three") is a rimless, bottlenecked, centerfire intermediate cartridge. It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create ...
However, the ammo was much heavier (393 gr (25.4 g) for 7.62 x 51 round compared to 160 gr (10.4 g) for .45 ACP), effectively limiting the ammo load. Additionally, when fired in full automatic mode free recoil delivered by full-sized and full-powered cartridges became an issue, too.

The bullets were typically short, light, hollow-point designs intended for maximum velocity and ranges out to the maximum point blank range with fixed sights. Early cartridges were loaded with black powder, and many later converted to cordite or other smokeless powders , often yielding two similar cartridges with different loadings, such as the ...
Any errors in range estimation are tactically irrelevant, as a well-aimed shot will hit the torso of the enemy soldier. The current trend for elevated sights and higher-velocity cartridges in assault rifles is in part due to a desire to extend the maximum point-blank range, which makes the rifle easier to use.

After the shooting, Butcher, 35, allegedly stole the couple’s pick-up truck and fled the area. Officers found the truck the following day, at 2:20 a.m., in a hotel parking lot in Roanoke Rapids.
The .223 Remington cartridge inspired an international tendency toward relatively small-sized, lightweight, high-velocity military service cartridges that allow a soldier to carry more ammunition for the same weight compared to their larger and heavier predecessor cartridges, have favourable maximum point-blank range or "battle zero ...
