They are not the same. Diameter is twice the size as radius.
No. Radius is half the diameter.
30 feet Assuming you are asking about a circle, then the area is Pixr^2 where r is the radius. Then if 700 were approximately equal to Pixr^2 then 700/3.14159 would be approximately equal to the radius squared. This is about 223 (222.8 is a little better approx) Now the square root of 223 is approximately 15 so the diameter is about 30 feet.
A sphere's height will always be the same as its diameter.
30% of 223= 30% * 223= 0.3 * 223= 66.9
While they are similar, the cartridges are not the same, with slight differences in the shoulder angle, length of neck. It is safe to fire .223 in a weapon chambered for 5.56, but 5.56 ammo in a weapon chambered for .223 may NOT be safe.
yes, except 556 is written as 5.56 caliber (223) Actually, no, it isn't. Although the dimensions match, the military 5.56 cartridge differs from the civilian .223 in several aspects, such as the neck angle, casing thickness, and chamber pressure. A general rule of thumb is that .223 Remington can be fired in a 5.56 chamber, but 5.56 ammo should not be fired in a dedicated .223 chamber.
In terms of power, or diameter? A .22 has a bullet diameter of .223 inches, the same as the .223 Remington and 5.56 military cartridge. The .222 Remington actually has a bullet diameter of .224 inches.
.223 inches in diameter, typically 45 to 55 grains for the .223 Remington, and 80 grains for the .223 Wylde.
556 millimeters is 55.6 centimeters.
.308 is identical in diameter to the 7.62x51 NATO cartridge (although the two are not exactly the same). .223 is identical in diameter to the 5.56x45 NATO (and M193) cartridge (though, again, they are not exactly the same). The .308 is larger.
.223
.223 inches.
.223 inches for the .22LR, .224 inches for the .22 WMR.
No But the Caliber is the same but theres more powder in the 223
"The .223 Remington is a sporting cartridge with almost the same external dimensions as the 5.56x45mm NATO military cartridge."In short, 223 IS the caliber- .223 inches
Dimensionally similar, but they are not exactly the same. A firearm with a 5.56x45 chamber can accommodate the .223 Remington cartridge, but a firearm with a .223 Remington chamber cannot accommodate the 5.56x45 cartridge.
