First, my rifles do not have a round in the chamber when I climb into or out of my ladder stand, and my MZ does not have a cap on it. That said - and I'm going to take a lot of heat for this - I ALWAYS carry my gun into the stand over my shoulder instead of pulling it up with a rope. Over my shoulder (usually crossways diagonally across my back) the barrel is beyond/above my head. If I fall and somehow the gun goes off, the muzzle is beyond my body and pointed away. If I drop a rifle being pulled up by a rope, possible the gun hits butt first and goes off with the barrel pointed right at me up in the stand.
I know pulling up a rifle by a rope is pounded into our heads for safety, but in my opinion, that is a lot less safe than over my shoulder.
