This balling gun is molded from low density polyethylene, a durable plastic chosen to hold up to repeated use around the barn or pasture. It measures approximately 13.5 inches in length with a ribbed head sized to accept a single medium bolus, making it suited to larger calves and adult sheep. The gun ships as a single, ready-to-use unit with no assembly needed. In use, the plunger is pulled back to load a bolus into the head, the tool is guided through the side of the animal's mouth, and the bolus is placed at the back of the tongue before the plunger is depressed to release it. The animal should be allowed to swallow before the head is released. Sanitizing the gun between uses helps maintain hygiene for the next dose. The gun is manufactured in the United States.
