These two charts are from the Federal website. There's really not much difference, a gun sighted at 100 yards is also sighted in at 40 yards, and a 50 yard zero is also sighted in at 85 yards. You have to remember that the bullet crosses the line of sight twice, so in reality one is a 40 yard zero and one is a 50 yard zero.






What you'll find really weird is when you get a close shot, at 15 yards you need to aim an inch over a squirrels head. The distances between 5 and 25 yards are worse than trying to hit between 50 and 150 yards.
