I was waiting to shoot a stand at the local sporting ground yesterday, when I witnessed an odd thing. A chap shooting the stand had a 'gun malfunction ' ? He had shot and killed the first target, but the gun , a Browning, had failed to fire the second barrel. He took the gun, from his shoulder and then, whilst still closed, holding it upright, bumped the heel of the stock on the front support bar of the shooting stand. He then remounted the gun, and proceeded to shoot the second target. He finished the stand without further incident. A couple of stands further on, he did the same thing. This time I stopped him from banging the gun on the cage. I asked him to take his right hand away from the grip, then prepare to take the shot again. He was convinced the gun wouldn't fire, but of course it did. He was not fully releasing the trigger between shots. It's often caused by tension as I know from experience. I then deliberately showed him, using my gun, exactly what he was doing. It transpired he had been advised by 'experts', that if this occurred, he should bang the heel of the stock to make the gun switch barrels. He agreed to try taking his finger out of the trigger guard, if this reoccurred, which it will, bug I don't think he was 100% convinced. I went on to try anx explain that jarring a loaded gun in such a manner, was a recipe for disaster. It can cause the gun to fire. I shall be watching for him in future !
