I like to find my "once fired" brass just off to the right and behind my position as I fire factory rounds! I have purchased "once fired" brass that had cracks in the case mouth from too many poorly done reloads. Gone are the days when police and military shot new out of box ammo, policed up their range, and the truly "once fired" brass sold as surplus crown assets. Anything today called once fired is best described as "unwanted".
