I find the African Carry to the the most comfortable way of carrying a double rifle. I go to great lengths to avoid "sweeping" anyone with the muzzles as well. Just because the barrels are facing "generally" forward, doesn't necessarily mean they are pointing at the guy in front of you. In the AC, the muzzles naturally point off to the side. If carrying on the right shoulder, they point about 45* to the right. If the line sweeps left, no problem. If the line sweeps right, either switch shoulders or more often, pull the forehand into the body and point the muzzles down until the line sweeps back left. This allows me to always know where the muzzles are pointing. Likewise, when turning within close quarters to other people, again, pull the forehand to the body and point the muzzles down. It works like a charm.

OK, so what if I fall. Well, if I have the rifle on a sling and I fall, is there any guarantee that the rifle is less likely to AD? And in that situation, I have no control of the barrels during the fall. You can "what if" the situation all day.

For the folks who think the rifle cannot be brought into action from the AC in a timely manner, I ask, Have you tried it? I find it exceptionally fast. Just a downward movement of the barrels and the rifle comes off the shoulder, muzzles down, the left hand grasps the fore end, the other hand slides back to the pistol grip, and the rifle spins in the hands with the butt rising to the shoulder. Takes less than a second and the gun is in perfect control the entire time.

I don't find the AC method to be quite so handy or comfortable with a bolt action however and tend to use a sling instead under those circumstances. Especially if the rifle is scoped.
