If you own full size goats, this bolus gun needs to be in your supply box! It is a little large for young goats, but excellent when using a larger capsule, such as a Cobalt capsule., for adult goats. I think that it is too large to use on the small breeds. The plastic head is great for preventing abrasions to the inside of the mouth when using it. I just used it on 85 meat goats. Hambry has the best prices, helpful employees and a very easy and quick order system. I highly recommend them.
