Why not figure out what ranges you plan on shooting at; what you plan on shooting at; what pellets you plan on shooting, and what speed they will be flying at and then zero accordingly. I have my Marauder zeroed at 30 yards which allows me not to spin my turret or mess up a range estimate anywhere from about 18 to 40 yards on a squirrel. I figure I can do better than that. With the added benefit of not doing anything to punch paper at 30 yards.
