I think your buddy should consider shooting distances. 100 yards? 200?

Will he be on foot? Horseback? ATV?

How well can he handle a semi auto rifle? Bolt action? Lever action? Single shot?

Answers to those questions MAY help in deciding.

A good alternative might be a Ruger Mini Ranch or Mini 30. They aren't known to be the most accurate rifles but will do just fine around 100 yards.

If 223 is legal to hunt with there stick with that. Or go to the Mini 30 and 7.62 X 39. Other calibers are great but you must consider the cost compared to 223 or 7.62.

The Rugers are a little spendy but can be found used. But it's an investment that will serve him well for many years.
