I do have 308 Howa in chassis. Nice shooting rig and really heavy. I looked in Howa new offering HS precision. But even with light barrel it weighs 8lb.The Ruger is 8 lb rifle naked. Not sure what your budget is but have you looked at Weatherby or even there Vanguards?
Savage Long Range or ?Check out Savage and Browning's Hells Canyon LR versions. Think the Savage runs just over 8lbs and Browning's is even lighter.
For sure it great rifle! But cost twice more that Sendero.I have a Christensen Arms ridgeline in 300WSM that shoots .7-.8 MOA , with factory hornady 200 GR ammo. Light and muzzle brake tamed the recoil , just remember hearing protection
Savage Long Range or ?
