Depends on the terrain. For a day of deer hunting in rolling hills with mixed vegetation, within a couple of miles of the truck, I'll carry a 15 lbs rifle. When sheep or elk hunting in mountainous terrain, my preference is 7lbs or less all up (6 lbs doesn't hurt!). Those would be the two extremes, I've carried rifles anywhere in between those weights, depending on application and terrain, and am happy to continue to do so.
