Can someone tell me exactly how to use and how they should react. Put all five in magazine? Then pull the trigger and then ???? will the Snap Cap pop out or will I have to remove it from the gun and then do it again until all five have been used and then reload the magazine? I guess I am asking will the snap cap pop out or will I have to remove each time? OR can I rack it and then just keep pulling the trigger on that one Snap Cap. Sorry for the simple question but I do not know so am asking.
