A plug scoring gauge is used on doubtful shots.

• A. False
• B. Not used
• C. It is never used
• D. True

Answer: (D)

When results are uncertain, you rely on an objective measurement tool to make a clear decision. A plug scoring gauge works like a go/no-go standard: you select gauges that represent the permissible size range and test the shot against them. If the appropriate gauge fits smoothly, the shot meets the tolerance; if it won’t fit, it’s out of tolerance. This approach removes guesswork and gives a definite pass or fail for doubtful shots, which is why using a plug scoring gauge in those situations is the right choice.
