Re: Low/High-Tech Military Air Guns

The main reason we use explosives is energy density; an airgun with the energy of a conventional rifle will be at about 1/4 the speed, 4x the recoil, and 20x the weight per shot (including tank weight on the airgun, and case/propellant weight for the conventional gun).

That is enough juice to shoot completely through an elephant and kill the elephant on the other side.

Really?

Certainly not from a GURPS RAW perspective.

IRL if find that my Horton Legend crossbow [165 lbs draw, 305 fps] has enough penetrating power to almost over penetrate a goat shot broadside to the chest [10-12"]. The fletching tends to stop the arrow from completly over penetrating the far layer of skin.

Yup. With a powerful compound bow, complete pass through on critters as big as grizzlies and moose is common provided no bone is hit.

Even fairly light bows can put arrows through a deer sized animal unless you dead center the shoulder joint.

Really nice bull elephant taken by Dr. Jan Seski with one Ashby tipped arrow. The bull was quarteing away at 20-yards. The arrow struck high in the crease, traveled between ribs on the near side, cut completely through the top of the heart, then kept going out the other side, once again, between ribs. The ivory was 50+# per tusk. Congratulations to Dr. Jan Seski on another fine elephant with the bow and arrow.

Terminal behavior of arrows would be impossible to accurately model and have it remain playable.

Your arrow is probably pretty light too.
