The Definition of Chapman Stance
The Chapman stance uses the same push-pull tension which defines the Weaver,
but instead of both elbows being bent, the gun side elbow is held straight and locked in place.
Assuming a right-handed shooter, the right arm is punched straight out, while the left elbow is bent and the left hand pulls back to provide tension. As a result of this change, Chapman gets its stability
from both muscle and skeletal support. This makes it a little more friendly than Weaver for those who lack upper-body muscle strength.

Plugs of hardened steel, precisely machined in relation to the standard dimensional specifications of a given cartridge,
normally in sets of three: "GO", "No-Go" and "Field". By loading these plug-gauges into the chamber in succession,
one can check that the action should close on the "Go" gauge. It should not close on the "No-Go" gauge,
but might were enough force to be used. And, it absolutely should not close on the "Field" gauge.
