Barrel weight is more strongly dependent on contour than length. A thin barrel can be plenty light, but when you are shooting factory ammo, the thin whippy barrels can have suboptimal accuracy for long range unless you can tune a handload into an accurate range.
My rule of thumb is that every 100 yards beyond 200 yards doubles the difficulty of a shot. A 600 yard shot at a game animal is 16 times more difficult than a 200 yard shot once inherent accuracy, shooting skill, wind drift, terrain, and range determination are all factored in. There are trade-offs in how that difficulty gap is bridged and it can be done reliably with either a light $3000 rifle or a heavy $1000 rifle with factory loads, but if you want to do it with a light $1000 rifle, you probably need to tune your own hand loads or else spend a lot of money trying 5-10 different factory loads until you finally find one that shoots well.
Personally, I've climbed up and down mountains with 12 lb rifles and also hauled thousands of pounds of meat out of difficult places. It seems silly to me to worry about a few more pounds in the rifle on the way in when success means hundreds of pounds of meat on the way out. My longest range rifle weighs about 18 pounds including the scope, bipod, and loaded magazine. Most real 600 yard rifles are going to weigh in at least 12 lbs. Unless the machining is excellent and all the tolerances are very tight, most 8 lb rifles are going to be shifting first shot cold bore point of impact all over the place with changes in temperature and altitude.
