I have yet to see one up close so my opinion is about worthless but based on their track size and my observations of them I really wouldn't have an issue hunting them with a .223 Rem, or anything else for that matter. That isn't a cartridge recommendation, just an observation of their size.
OP, if you're going guided then this shouldn't be an issue but if you're planning a DIY hunt, do some research in judging the darn things. I could have shot several in NM last Feb but just never found one that I really confidently thought was a ram, despite looking through a lot of manuals and watching a lot of videos.
