If this wasn't about arbitrary exclusion at the core of it, no one would be arguing about which sort of tension driven projectile is sufficiently technologically backward to count.
SD Bob, while I can't argue with the point that if something is double lunged it WILL die, I will say that it is less likely that an arrow will go through both lungs in comparison to a projectile from a rifle or shotgun.
Go with at least a .277 dia with a 150+ grain projectile with good terminal ballistics characteristics: mass retention and expansion (see Barnes or Nosler)
Now, enlightened to what the utility of that extra powder is for, I use a 200 grain projectile, and drive it just 300 fps slower.
Follow me on this … They fire a projectile from a ship 40 miles off shore at a very high velocity - maybe it should take 5 minutes to impact.
In the short story “Small World” (1978), by Bob Shaw, for example, a projectile is described as travelling across a cylindrical space habitat along an S-shaped trajectory.
Very often, I won't even care what shape my projectile is (I'll just assume it to be a point-mass).
For example, if I want to come up with a general theory of projectile motion, I don't have much need for information about what my projectile is made of or how much it costs or what color it is.
Unlike current Taser guns, this projectile is fired out of a shotgun.
The biggest change you're going to see is the way in which we launch a projectile from a barrel.
