(based on 1120 fps, 124 grain 9mm. If you assume your carbine gets 1400 fps, zero 1 inch high at 25 yards... -1.75" at 7yards, +2.5" at 50yards, +1.5 at 75, -3 at 100. The trajectory matters a bunch past 50 yards or so based on the muzzle velocity. I'd be inclined to, say, split the difference at 25 yards, call it about 1.5ish. You'll be low until 17 yards or so, high from there until about 75 yards, and slightly low at 100 yards. Or, just get Modern Ballistics from Joe, and figure it out yourself. :) According to Joe Huffman’s Modern Ballistics, if you zero it two inches high at 25 yards, you’re about 1.25 low at 7yards, three inches high at 50 yards, about dead on at 75, and seven inches low at 100 yards.

If you assume your carbine gets 1400 fps, zero 1 inch high at 25 yards… -1.75″ at 7yards, +2.5″ at 50yards, +1.5 at 75, -3 at 100.

I'm not so good at figuring out optics and ranges. Yeah, you people who understand this stuff annoy me. I’m not so good at figuring out optics and ranges.

If you adjust the sight dead on at 25 yards you should be only about 2" low at 7 yards. Just sayin'. Looking at your drawings I’d guess that you’re rifle shoots about 7″ high at 25 yards?
