Yup. A friend runs guided caribou hunts in the NWT. All the guides apparently now use CRF guns after an inuit guide was mauled by a polar bear, as they will feed in any orientation. Push feed guns aren't known to feed well when the rifle is upside down or the ejection port is angled downward.
I use to believe that push feeds will not reliably feed upside down or ejection port down as well....that is until I got bored a few weeks ago and gave it a try with a 700 in 30-06. Inverted, port up, port down, rifle face up or down, feeding fast, or very slowly, the Remington 700 feed 100 % reliably every time.
