There is a happy medium for me, I have packed very light rifles, and heavy ones, it’s all a compromise… the type of hunting you do matters as well.
If I’m covering an average of 10 mountain miles per day, and know my shots will be under 250yds, I may pick a different rifle than a hunt I’m covering 3 miles and know shots are likely to be over 400yds… the perfect balance is different for all of us.
I think a person who covers a lot of ground in the mountains and shoots a lot in the off season can benefit from a light rifle.. someone who shoots a box of ammo per year and mostly road hunts with some short hikes would benefit from a heavier rifle
I seem to like that 8.5-10lb range, I like packing a lighter rifle, but they are harder to shoot well in field positions and hurried shots (for me) since I started using a gun bearer, I have started favoring a little heavier rifle, it’s still weight, but how the weight is carried matters.
My bow setup is light, and that’s due to the hunting I do, I cover a lot of country, and know historically my shots will be sub 20yds shooting at a big bullseye, don’t need a target rig for that.
It’s not about light or heavy, it’s about finding the right compromise for the hunting you do, there is no one size fits all here
