The XWR’s have worked well for me in .308 and .300 Win Mag. They will cut cloverleafs with TTSX, GK, SMK, and BT’s.
I’ve bought a few rifles cheap when the owner thought they would not work. Two “bad” rifles had Leupolds and one had a Zeiss.
Shot them, yep, they were like shotguns.
Check torque on the action screws (should be 45 in/lbs), clean the barrel, quick change of bases, rings, and scope to a Pic rail with a known Nightforce scope and Nightforce steel rings with some good ammo and magically the rifles shot very well.
