Original: Shotgun Choke Cone Plots, posted April 24th 2014
I made this thing, and thought I may as well post it here:
The plots scale with the browser window, so adjust your window to make them square. Scale is in degrees, assuming a base pellet cone of 3 degrees (870 buckshot). Other shotguns pellet cones will be proportionally the same, just with a different scale.
The plots for the different chokes each have their own sheet. The last sheet is the data sheet that makes the whole thing work. (hint: it’s tons of randomly generated numbers)
