We have made a great pellet tray for shooting ISSF air pistol and air rifle.  This tray is a great way to organize your 60 pellets for a match.  We utilized our 3d printer to create a tray that holds your pellets secure enough that you can shoot your match without counting pellets. Olympic style 10 Meter air pistol starts with 60 shots.  This tray allows you to organize your shots in six rows of 10. This is designed for .177″ pellets.
