Sendero, and other similar builds/wt, in 300 RUM, bipod, stock cheek riser with ammo pouch, 20 moa base with 6-24x50 in 30mm tube, and sling. The weight does require my aging body to shift carry shoulders from time to time, but when it is time to to shoot across, up or down the canyon, the benefits of a stable platform are worth the price of admission.
Now for a real test, try carrying, or lugging, a couple of my laminated stock LR varmint rifles up and down Colorado hills in search of chucks and smaller targets. Full bull 26" barrels, heavy full size tactical or prone stocks, bipods, 6-24x50, 8-32x50 or 10-40x52 all 30mm tubes. Once a group of targets is located, the pain of carrying logs around soon disappears.
