Help: My favorite 12 gauge a 1913 Westley Richards Drop Lock 12 Gauge that was completely redone by Westley Richards in 1971 doubled on me in the dove field. It has not done it before or since. I tested it again with live ammo, at the risk to my arm, and with snap caps but no issue. However, doubling on a 6lbs 12 gauge is a bit scary. Anyone have ideas or know a person capable of checking the gun out? thanks, Huntersdad.
