A friend and myself were working on a hammergun that had broken a main spring and had taken the lock out because the new one was to strong. The lock was laying on the table with the spring side up and had been for 4 or 5 minutes when the spring broke in 3 pieces and flew up and hit my friend in the face. We had shot 3 rounds of Skeet so I thought the spring should have broken then rather than on the bench with the hammer in the uncocked position. Anyone ever heard of such a thing? Mike
