Hand Cannoneering

The act of (re)loading ammunition as powerful (in the gun community: "hot") as possible. Then proceeding to fire such ammunition. Usually done with handguns, hence the "hand."

Derived from "Cannoneer", a dated term for operators of artillery. Also from the "Hand Cannon", the first true firearm invented in China around the 1300s.

Ian: No thanks, I really like being able to use my wrists.
