This year I used my Gun Bearer (4th hunt with it) and had my Ruger American Predator with the scope in a downward position. Also I carried the butt with the Gun Bearer butt pocket attached to my pack's hip belt as far rearward on my right side as possible.
This put the barrel further away from my head and made the rifle easier to carry. Thanks to guys on this site for that advice.
I need to use both hiking poles and the Gun Bearer has made this possible.
P.S. Compared to an Eberlestock type rifle pouch (between the pack and your back) the Kifaru Gun Bearer is not only lighter but far quicker to get a rifle up and on target.
The downside compared to a pack rifle pouch is that it is not protected from the elements or from falls like an Eberlestock pack pouch.
If you're ski or snowshoe hunting a Gun Bearer is absolutely essential so you can use ski poles for stability. I've hunted both ways (with climbing skins on the skis, BTW) and you can't carry a rifle in your hands - even when snowshoeing. Climbing around obstacles requires ski poles.
The speed at which you can bring up your rifle from a Gun Bearer is Warp Speed compared to pulling it up and out of an Eberlestock pack's rifle pouch.
