"Finland red, Germany black, Egypt white."

 

      Keep in mind that some of these weapons have different damage values than the numbers found in Call of Cthulhu. We're using the Taylor Knock-Out Factor (TKO) as the basis for comparison, by the way.

 

TKO

less than 2.25

1d6

2.25 to less than 4.5

1d8

4.5 to less than 9

1d10

9 to less than 13.5

1d10+2

13.5 to less than 18

2d6+2

18 to less than 27

2d6+4

27 to less than 36

3d6+2

36 to less than 72

3d6+4

72 to less than 144

4d6+1

144 to less than 288

2d10+4

288 to less than 576

5d6

576 to less than 1152 5d6+2

 

     On the chart below, "pen" is the maximum penetration, the most armor that the bullet can get through.

Instead of 1d10, like the other ammo at that TKO level? Note that 2d8 isn't even on our chart -- 2d8 is the legacy, traditional number for "M16 bullets" in Call of Cthulhu. We can call it the effect of "M16 bullets tumble" or something, but really it's ( a ) the "way it always has been in gaming", and ( b ) the Taylor number is an overly-simple calculation, meant to give relative values for big African game cartridges. 2d8 seems to fit the "place in military usage" better than 1d10.

Question: 5.56 NATO ball ... How do you get from a TKO of around 6.25 to 2d8?
