Nothing odd here, it takes that high at 50 yards to land 'em on zero at 100. Snake's trajectory finding back up exactly what I have done before and what the ballistic calculators predict. Try shooting match ammo with a 100 yard zero; you'll be closer to 5'' to 6'' high at 100. The flattest shooting .22 long rifle I've ever tried has to be CCI Stingers. Zeroed at 75 yards put them right at 3/4'' high at 50 yards and 2'' low at 100 yards. I'd bet that a 100 yard zero would put them about 2-1/2'' to 3'' high at 50 yards midrange trajectory, just like the ballistic information predicts at CCI's website.

If a person wants to shoot much flatter than that, it'll take going to the .17 HMR. 100 yard zero gets you about 1/2'' high at 50 yards. You can set it up to about 1/2'' high at 100 yards and still be less than 1'' high at 50 yards and only about 2'' or so low at 200 yards. The .22 long rifle is effectively a 65 to 75 yard cartridge. Going further with it requires intimate knowledge of the trajectory and an ability to judge distances accurately (or a laser rangefinder).
