if you hold the PF at an angle (muzzle up) with the ejection port down and push the bolt foreward just far enough to strip the top round from the magazine, then retract the bolt, said round simply drops out (into your hand if you have a clue)
if you lower the firing pin onto a loaded round, the mainspring will apply constant pressure on the primer and could easily cause a ND. i have never seen this method called safe by anybody with a clue.
and i handle rifles a bunch more than you do.
