Hmmmm, At that range, caliber and grain of bullet, IMHO as long as she is very familier with the rifle, and has lots of practice...it should/could be a great outcome. Good Luck to her!! Personally I would not use anything but my .06 Not because I am not confident, but I want a dead and not wounded bear...that is just me though. If she feels good with her shot placement, she should be just fine.
