I keep an empty breech until in the firing zone, then one up the tube and (tested) safety on. I empty breech if moving from zone.
I also carry rifle with muzzle pointing behind me if I'm #2 in the hunting party and one up the spout . . . . . (if there's a reasonable chance there'll be more than the 1 shot)
the country/cover dictates a lot. It's too easy to knock a safety, or lose a round from bolt on 1/2 cock.
