Hunting with a round in the chamber is a common practice.
My Mate usually loads one in the chamber, and decocks the bolt by pulling the trigger. (bolt doesnt catch)
While able to hunt ‘safely’ by having no firing pin underload. When you see an animal all you need to do is rack the bolt up n down.
Although one time, as he went to uncock it, it went off. Over my head.
#1 and only rule, always point it in a safe direction.
