Something I think a lot of people that lose sight of:
Not all precision rifles are hunting rifles, and sadly, not all hunting rifles are precision rifles.
Many hunting rifles can be both light and incredibly accurate, look at the Rifles Inc Lines; however, they don't have the weight or barrel profiles to shoot all day. Precision rifles you could shoot all day comfortably and without any noticeable change in POI; however, I wouldn't want to do any real hunting with with a heavy, purpose built precision rifle.
