I've been using a Nikon Monarch 5 x 15 44mm on a 270win. It has 48 moa of adjustment. Zeroed at 200 yds. At 5x it does a perfect job at the close-in shots. I put a 20moa rail on it and found the scope did not have enough down elevation to make it work so my smith put 2 shims under that which he said put the tilt at about 13moa. The scope tracks very well through all the adjustments. I don't have 1000yds to shoot but I do have 850 and it hits sheep sized steel at that range without any holdover using 15x and dials back to zero perfectly. I don't know if they are still available but the cost wouldn't break the bank.
