Springbok at Jules of the Karoo

We have 4 breeding rams which have been measured in excess of 18 inches...these is one or two other ones we think would push 18 inches as well. In the attached image is breeding ram we measured last year... at time of capture he measured just under 18,5 inches... one can clearly see that he has gained at least another half inch since then. At time of measurement he was just over 3 years old...
