With price as a consideration, I'd second the TT operator pack. I don't have that specific pack but when I go out to shoot on open land and take along all of the items you mentioned you were wanting to fit, I have a ruck that is the exact same CU size as the TT. I sling my bolt gun, have my tripod on one side (if I think Ill need it), spotter on the other and then my LRF, ammo, reference materials, 3L bladder, basic snivel gear (jacket, gloves, neck gaither, watch cap) and my misc shooting equipment. It all fits and theres a little room to cram in more, or use the molle for additional pouches like I do with my Kestrell and additional water bladder.
