I recently purchased a Winchester 70 in 375HH. I have a Swarovski 1-6 mounted on it and have found it very nice to shoot. I am using 300 grain TSX factory ammo and my question is what distance is best zero. I am headed to Zimbabwe in spring for PG with most shots likely maxed at 200 yards. Yesterday I zeroed for 150 yards which seems to be best but would like your inputs.
