Eliminate Extraction Problems Before They Start
Allows the gunsmith or shooter to accurately measure extractor/shell rim tension to help achieve reliable case feeding, extraction and ejection. Place the double-ended gauge between the breech face and the extractor. Hook your 6 lb. trigger pull gauge through the Tension Gauge's hole and gently pull until the Gauge releases from the extractor. The trigger pull gauge shows exact amount of rim tension.
