In the current Handloader has an article on the 338-06 AI the author states he shot one in NM that weighed 600 Ibs. I had thought 300, but this made me question that since I have never seen one, but would like to hunt them sometime.
a 600 pound Aoudad should be lumped in with 8 foot rattlesnakes,1200 pound elk and 2500 pound cape buffalo.
