The subject of this study is a ballistic analysis of the prototype of the new compressed-air projector Zoosleep 16/5® (Z16/5). The study was conducted at an indoor shooting range at the National Proof House, at Süßenbrunn in Vienna, Austria. The prototype of Z16/5 has a barrel with a diameter of 16 millimetre (mm), a length of 94 centimetres (cm) and weighs 3.8 kilogrammes (kg). A hand-operated pump is located under the barrel and the projector has a digital display which displays pressure settings in bar, allowing for precise adjustment. The projectile is a two-chambered compressed-air dart with a volume of 5 millilitre (ml). This is an advantage, because higher volumes of drug can be delivered to the animal. The way to transport the projectile is different to other projectors. In this projector the projectile is pulled from the barrel due to the construction of the stabiliser. Precision, accuracy and impact energy of the projector and the projectile were determined. Precision is defined as high when projectiles are tightly grouped together on the target. Accuracy is defined as high when all projectiles are tightly grouped around the bullseye of the target. The Z16/5 demonstrated good to average results compared to the predefined thresholds. It has been suggested, that impact energy should not exceed values higher than 20 Joule. At longer distances the projector falls short of the recommended value. All results were compared to other CO2/air-powered projectors. The outcome of the comparison was variable.
