Not sure why anyone would shoot off hand when you could (and should) be using sticks.
Because they have mastered the skill, they know how to shoot a rifle, and executing well aimed shots on certain shot presentations would be handicapped if sticks were used.
My take on this has always been I'd never try it. Just flat to much risk to wounding game which I think they don't care about.
I've shot moving targets, with the AR, and we used to have a match that was a blast at moving targets at 300, I got to where I knew how much of my front post to lead with and could really rattle em off.
That being said, the shooter moving, the gun moving, the game moving AND obstacles in the way... thats beyond my personal ethics by far.
We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
