My latest build, a Bartlien No 2 barreled, Savage 11 Lightweight Hunter Action in a prototype Manners Stock (pillar bedded by the owner of Manners no less) with Talley one piece rings and a 1" diameter tube side focus, non illuminated Vortex Diamondback comes in at just shy of 8 pounds with 4 rounds loaded.

I'm real impressed with the diamondback, it tracks flawlessly and has excellent glass and the BDC reticle. Granted, it's a 308 however, loaded properly it's still viable to 500 yards which, in all honesty is about the farthest I'm going to ethically shoot anyway (and most times lots closer, even out west.
I own one of those Kuhuna rifles too. It's a tank. Sure it shoots out to 1500 yards and your wallet groans everytime you touch it off, and it wears a 30mm long range scope illuminated of course, but candidly, I much prefer the easy to shoot and load for 308.
At my age, 'pie in the sky' can stay there. I'm about reality and the reality is, I'm an old fart and I need lightweight tools to keep doing what I enjoy.
