Keeps me from getting tired so fast hiking with a rifle on a sling. It is hard to hike comfortably with one shoulder sckrunched up to hold the rifle sling. In a pinch, you can use a glove, a rolled up camo mask etc....anything that will make a bump on the end of your shoulder. This one litttle trick helps you move better with a more natural swing to your arms and your whole body in general, and so, is pleasant to hike, instead of feeling like work.....gives ME a better attitude in general. Being in the woods should be fun...not hardship.
