Loaded up to the max, they are serious chuck bombs, minimal hazard as they pretty much detonate on impact. Backed off a bit they would certainly do the trick for your friend, but a
shot quartering on or away might not be so good.
If you haven't spent the money yet, the 85gr Sierra BTSP works real well, and is designed as a medium game bullet. I found it a bit frangible on close shots with full power loads, but great on antelope at 200yds +. A medium dose of 4895 or 4064 for 2800fps or so might be just the ticket. If you can find some.
