A gun is either on the face or off the face.
It's a pass/fail test. Like pregnancy.
Burrard writes of examining used guns for purchase and states that sometimes it's possible to see daylight through the barrel/action interface. He indicates this is an 'off the face' condition.
The Major states that further damage is caused by continued use in an off the face condition.
Accidents are possible. Split rims may occur. Gas jets may cause erosion or outright failure.
This is not new information.
Fix the gun, don't shoot it.
