That's a personal question!
It depends on HOW you hunt, WHERE you hunt, and your own personal tolerances.
If you walk 500 yards to a stand or a blind across flat land, then a big heavy gun isn't a problem.
Other end of the spectrum is backpacking a full day up into the mountains and setting up a spike camp to hunt. In that case I'd like a very light weight rifle.
Much of the time I find myself going through steep coulees flanking the milk river, or out in the mountains in very steep terrain. I'll hike all day sometimes and cover 25km or more. I like light rifles. I don't have the $$ to get a custom-built rifle weighing less than 6 lbs scoped [but that would be nice] but I do have several rifles that come in under 7.5 lbs scoped. Those are about right for me. When the gun gets about 8.5 lbs with scope, then I'm not too keen on it.
Lots of guys pack around rifles weighing over 10 lbs and are perfectly pleased with them, even if they are covering a lot of country on foot.
Like I said... it's personal.
