I have dots in quite a few scopes.. As you pointed out they are great for varmints, but not so hot on big game.. I do have one 3-9 Leupold that I set up for my old .300.. It has dots from 200-600 yards.. BUT the 200 yard dot is pretty big, too big for serious varmint shooting, but other than coyotes, this was a big game rig..
