Sizes are often expressed as a fraction of an inch, with a one in the numerator, and a decimal number in the denominator. For example, 1/2.5 converts to 2/5 as a simple fraction, or 0.4 as a decimal number. This "inch" system gives a result approximately 1.5 times the length of the diagonal of the sensor.
The 9.3×74mmR is of a rimmed, bottleneck design and uses a .366-inch (9.3 mm) diameter bullet, usually weighing 286-grain (18.5 g). According to Hornady, at this weight the velocity is 2,362.20 ft/s (720.00 m/s) and energy is 3,536 ft⋅lbf (4,794 J). This cartridge is used for hunting medium to large game animals and is very popular in Europe ...
