Using the Africa carry method I've never had trouble not pointing the muzzles at anyone. Whether in a group or not. It's quite easy to angle the muzzles away from anyone. Often on safari everyone walks in a line. Usually a tracker the PH, then the client. Others behind unless they spread out to search for tracks. Easy in a line to angle to the left or right.

Funny the advice to use a sling. Others claim a sling should never be on a dangerous game rifle.

Certainly a sling gets in the way in thick thorn jess.
