When asking opinions on the forum you'll get a wide range of answers. So here's my *opinion*
I think I'm one of the few guys that feels there's such thing as too light...
It could be mental or poor form but I feel I sway less with something not super light if I have to shoot with no rest. And for hunting beyond 400 yards I'll take a heavier gun because at longer distances I feel I'm doing more glassing and less hiking.
I am no expert by all means, and it could be me but I have a couple buddies that say the same thing.
Furthermore like some others already stated I don't feel like there's massive performance differences between $1000 and $2000 rifles. More aesthetics or paying for a lighter gun. I rather save money and get less aesthetics and just spend more money on the glass.
With all that being said I shoot a bergara b14 wilderness hmr more then anything else. And yes it's a freaking tank and everyone I know that's felt it said they'd never hunt with it and I'm crazy. If you're wanting lighter I'd just go with a different b14 wilderness, I am a big guy so the extra weight doesn't bother me and it's what I shoot better with. The b14 wilderness hunter is about 2lbs lighter so that might be a great option to look at.
I've shot plenty of tikas mostly 270 wsm, 308, and 7mag and my personal preference is the bergara.
If I ever decide to go beyond what that bergara gives me then I'll likely leap up to custom and spend a stack of money or get one of the half moa guarantee rifles from Christiansen arms. I only say CA because I have a buddy with one and it's the only rifle of that quality I could shoot and fondle before spending that much money.
