If your original question was about how rifleman's rules relates, theoretically, to the parameters of distance and gravity, it doesn't. It's an empirical approximation.
The same question was posted recently. Check the "similar threads" section below.

It is probably better to find a current model that fits the budget rather than an older one.
This is true of most tech, to ensure you get adequate product support. And also Moore's law.
Had a Highlander and never made use of the third row; it cuts into storage space too much. Worked fine for two kids and two labs if you have a cargo topper.
When we had our third kid we got a Sienna.
Just got over a three day fever. Deadlift PR single today. You never know...
deadlift 1/3/3/3/3 @ 94/86/82/82/82%
pause bench 5/5/5 @ 9/8/9 RPE
feet up bench 10/10/10 @ 8/8/8 RPE
calf raises 4x20
superset tri pull 3x16 / curl 3x14
It is often measured as a grip-to-trigger distance. However, since the geometries of riflestocks vary quite a bit, I think it's better to measure this qualitatively. I.e. can you get perfect trigger control with your hand comfortably on the grip of the rifle?
As I understand it, bullet expansion is largely dictated by drag, and drag is proportional to velocity, but independent of mass. Therefore it is not useful to include energy in the discussion of bullet expansion.
Do you have a case gauge?
I would not reload once-fired .223 without one, unless it was fired in my chamber. The case dimensions in range pickup .223 are allover the map.
CIP headspaces the cartridge the same way, the callout is just different.
They are essentially the same based on the drawings. How did you figure that CIP is longer?
