As a guy who has shot heavy for caliber, TIPPED, match bullets for game, I would not use a Scenar, especially a lightish Scenar at that.
I'm much less concerned with over expansion as I am with underexpansion. I've never seen a heavy match bullet cause a surface wound, but I've seen SMKs go clean thru stuff without making a decent size hole. I've also heard of Berger's doing the same, tho my experience differs.
At this point there are lots of good hunting bullets tho, and for the most of us dont NEED any of the advantages of match bullets. I agree with the others pick out any of the "hunting" bullets and go from there.
If you already load and shoot the Scenar, and only want to hunt with your rifle now and then, I'm not even sure I'd stock another bullet type. I think I'd simply buy a couple boxes of factory ammo when I wanted to hunt.
