At school a dial indicator was placed against a barrel. A pencil then pushed against the barrel with the resulting jump displayed by the indicator. Lesson: no pressure on barrel but if there is, make it consistent. You want consistent harmonics for consistent shot placement. Sometimes minute of mastadon is not good enough.
