this table is set at a sedate 2800 fps and a 140 grain nosler ballistic tip bullet which is easily obtainable and a zero of 250 yards. Some bullet manufactures advise that there bullets may or may not expand below 1800 fps. So if that is true we can let 500 yards be the max range for this set up to allow a safety margin.
However are you capable to shoot at that distance and experienced enough to gauge wind speeds for horizontal drift... If you do not shoot at distance a lot, do not try it in the hunting field.
250 yards looks like a good zero as you can hold center mass and keep your bullets inside the 9-10 inch kill zone on a deer out to 300yards with more than 3/4's of a ton of energy.
But remember bullet placement is the KEY factor here, velocity and energy matter, but not as much.
