If your buddy wants a new rifle then he should go get it, if he thinks he needs a new rifle, he's wrong. The idea of a "brush" gun drives me crazy. I can't remember a time in my life when I've said to myself, "you know, if only I had a rifle that shoots a bullet a little slower, and has 2 inches less barrel I'd have killed that deer." I've killed 2 deer and 2 caribou at extremely close ranges in the past few years, and I've never had any trouble with my .270, 30-06, or 300WM not working.
Get a 3-9x scope and shoot that 270 for everything you do.
