ShrtRnd asked a good question: How ultra is too "ultra-Lite"?
I shot my Kimber hunter 308 more accurately than I shoot my Kimber Adirondack 308. With my different scope choices, the hunter weighed 13 ounces more than the adirondack and for me that was just about perfect.
I have read many comments online saying Kimbers are not accurate, but in my experience they are very accurate. LIGHT rifles are just harder to shoot accurately than a heavy rifle. I can imagine that a 4 pound 7 ounce Howa would be even harder to shoot accurately, but with proper technique I bet it can be.
The recoil difference was noticeable too.
