Were you running a CTR as your buttstock?
One trick I've seen that works well if you have a CTR or CTR like stock is attaching the sling to the outside of the stock. So if you're right handed the stock attaches to the QD Attachment point on the right side of the rifle (side with the ejection port).
This makes it easier while choking you less
I learned a similar lesson at another carbine class. It works very well using that method and makes those transitions much easier IMHO.
