I recnetly bought a NEF handy-rifle for my niece to start hunting with. I sighted it in, but found that if I was on at 50 yds, I was grouping 6" high at 100yds. Zeroing at 100yds showed 4" low at 50 yds...My shot groups were decent. I checked the ballistics charts for the ammunition I was using, and there shouldn't have been nearly that much difference. Anyone have any ideas as to what the problem was?

Couple questions for you...
How high is your scope from your barrel?
What grain bullet are you using?
What barrel length do you have?
How well mounted is your scope?
What scope are you using?
Even still though that much difference is very extreme.

243 Trajectory

243 shoots way flatter than that. And this seems backwards. A 50 yard zero should group low at 100 yards, not high. It may be a parallax thing with the scope. If the scope is parallax adjusted for 100 yards, that means if you move your head from side to side while looking through the scope the point of impact will not change. It will change if your scope is parallax adjusted for 50 yards and you shoot at 200. Some scopes have a parallax adjuster on them and some do not. This is probably part of your problem. Also pay attention to your shooting position in both cases. If it is significantly different, this can alter your point of impact as well. Like if at 50 yards you shoot from a prone position and at 100 yards you shoot from the bench. I've even noticed that seemingly small things like grabbing the forend while I shoot from the bench vs. not grabbing the forend can move my point of impact by as much as an inch.
Also if this was two different shooting sessions it is possible the scope got knocked out of whack. Also pay attention if you were shooting up hill or down hill.

no problem. That's what all bullets do, some are just more pronounced than others.
if your zeroed at 100 meters then you will be 2 to 4 low at 50 meters and 2 to 4 inches low at 200 meters as well, depending on the caliber of the rifle and it's muzzle velocity. There are charts that will give you all this information based on caliber, bullet weight and power charge.
I would zero at 100 Meters and teach her to shoot a little high at close in shots as well as really long shots. Good luck

You are zeroing too close..... zero at 200 meters..... then at 50 you will be only 2 inches low and 100 meters 1 inch low..... also the grain of the bullet matters, use a low grain like 55 for the lowest drop in trajectory

That's a real puzzler, unless you topped it with a scope mounted way high above the barrel, like those stupid "see through" mounts they used to pawn off on the unsuspecting lever-action owners. If you've fallen for that one, it needs to be fixed quickly, mounting the scope as close to the barrel as you can.
