Good temp to cook at but from what I can see from the pics it does not look as done as it should. Was there recess of the bones? Trick is knowing what the ribs look like when you pick them up with the tongs on one end and see them when they bend over. Could be done well but hard to tell from the pics. Should not be falling off bone when you bite into them, it is a fine line. Have fun with it none the less.
