I just started carrying an Eberlestock backpack this year with one of the back scabbards. I think it's about the best money I've ever spent on hunting equipment. It keeps the rifle in the middle of your back, so both shoulders are carrying the weight instead of one. Both of your hands are free all the time, which is a huge plus for me because most of my hunting is for elk and mule deer above 8000 ft. in pretty rough country. If you walk a lot these things are great. It's also a lot easier to get to your rifle than you might think. The major drawback is that once you take the rifle out it's really difficult to get it back in without taking the pack off, or having some help. They are also fairly pricey, but for me it was well worth it to have my hands free and not have to worry about dropping a rifle because of a loose swivel stud.
