The most important part is that the barrel hits the user in the butt. The sling must be long enough to do this or you get jacked in the back or ribs. Notice how big the shotgun gets with the giant sling on it? It's impressive and impractical. I prefer the left shoulder African carry over this method. I can keep my loop sling fairly small and unobtrusive. I grab the forend and raise it to eye level and twist counter clockwise as the right hand grabs the stock right about at my left armpit. I saw this on the web and tried it and it worked well. Disclaimer: I grew up in a family of short barreled pump shotgun deer hunters so the African carry is very familiar to me.
