Are you running an angled base/mount?
What you are seeing is a peculiarity with 1x scopes (any <span style="font-style: italic">scope</span> starting at 1.1x or 1x that allows binocular vision with both eyes open) that is an issue with all such scopes, yet I've never seen this talked about anywhere.
The way a scope is constructed, the image you see will shift up or down when dialing elevation, so when looking "straight ahead" with both eyes open, there will be an offset between the "bare eye" image and the one the "scope eye" picks up. As long as this offset is small (meaning the scope being near optically centered), this is not an issue. The further you get from optical center, the harder it gets for the brain to get the two images to match. This is very much like looking through a misaligned pair of binoculars. (Note: this does not apply to red dot sights since they don't use an erector system like a scope).
Normally, dialing large amounts of elevation only happens at longer ranges, but you'll use higher magnification at those longer ranges anyway, so no problem here. The problems start when putting such a scope on an inclined base/mount, because then you're way off optical center at short ranges. The same thing might happen if the base is crooked and lots of elevation/windage from optical center is necessary to zero the rifle, but since you are mentioning that the image through the scope is "lower", I'd guess there's a good bit of forward cant in your setup.
Bottom line: <span style="font-weight: bold">Do not use an angled base/mount for a 1-Xx scope!</span> It's not a fault of your individual scope but a result of being off optical center at short ranges. You will be able to "dial away" the effect by cranking in a couple mils of elevation (adjusting for long range).
Distortion at the edge of the FOV is generally a property of the optical design and as such varies when looking at different models.</div></div>
