......put muzzle of rifle on floor so that rifle is in verticle position, with rifle in this verticle position raise bolt and pull all the way to the rear, slowly push bolt forward, at about half way forward your round will fall into chamber......
At what point might you deploy this practice while hunting or vigorously chasing your prey?
Personally,in 35 years of hunting I have never had a problem with a push feed bolt.I have never had a bolt of any kind jam.I never saw the need for CRF.I thought though, that the whole arguement for CRF was reliability of feeding from any angle,even if knocked down while hunting dangerous game.
To answer your question,possible while getting up, after being knocked down by something I or my guide should have already put down.
