I like to get up around timberline to hunt elk and I've never been one to sit for long and as we age I find now 8 1/2 to 9 1/2 lbs is about right for me. My 280AI weight 9 1/4 lbs and 284 is almost 9lbs same as the 30-338mag and I change packs last year when with the Eberlestock
X2 save little weight over my old one.
I've rebuild lot starting 7 yrs ago may not have that heavier contour on a barrel that I'd like but now that I'm 70 didn't give up all that much with the smaller contour also I had my fun with the heavy barrels.
build what you want is my advise
