Editing Shotgun slug (section)

=== Taylor knock-out factor ===
The [[Taylor knock-out factor]] (TKOF) was developed as a measure of [[stopping power]] for hunting game, however it is a rather flawed calculation.<ref>{{Cite web |title=Taylor Knock-Out Factor (TKOF) |url=https://www.chuckhawks.com/taylor_KO_factor.htm |access-date=2022-12-26 |website=www.chuckhawks.com}}</ref> It is defined as the product of bullet mass, velocity and diameter, using the imperial units [[Grain (unit)|grains]] (equal to 64.79891&nbsp;mg), [[feet per second]] (equal to 0.3048&nbsp;m/s) and inches (equal to 25.4&nbsp;mm):

: <math>\text{TKOF} = \text{Mass(grains)} \times \text{Velocity(feet per second)} \times \text{Diameter(inches)} \times \frac{1}{7000}.</math>

Some TKOF example values for shotgun slugs are:
* 71 TKOF for a 70&nbsp;mm (2.75 in) slug (i.e. 437.5 grain (1&nbsp;oz) × 1,560 FPS × 0.729 caliber /7000 = 71.07 TKOF)
* 80 TKOF for a 76&nbsp;mm (3 in)  slug (i.e. 437.5 grain (1&nbsp;oz) × 1,760 FPS × 0.729 caliber /7000 = 80.19 TKOF)

To compare with rifles, some TKOF example values for rifle cartridges are:
