You really limit yourself and the capabilities of your carbine / rifle with a 50-yard zero. For the majority of AR shooters, a 100 yard zero is most practical, regardless of bullet weight. The gun will shoot a little high at 50 yards and a little low at 200.

cyphertext- Simply stated, a 50 yard zero will cause greater bullet drop at 250 yards than a 100 yard zero will. What's stated in my original post is correct.
I suppose if we need to be more exact, specific bullets & weights, ballistic coefficients, and muzzle velocities need to be included, but the basic premise holds true.

still the best video I have seen on the subject
Well, maybe I should check my figures. I've certainly been wrong before. I didn't intend to infuriate anyone...
With a 50 yard zero, at 250 yards the impact will not be 9 inches low, it will be about 3 inches low as I previously stated. I suggest you read from the following...Just checked trajectory on a "Load From A Disk" program. I chose randomly a 55 grain Hornady V-Max, BC of .25 at 2800 fps muzzle velocity. With a 50 yard zero, at 100 yards the bullet is .22" high, and at 250 yards, it is 8.9" low as opposed to 9.4" low with a 100 yard zero. You're right, cyphertext.
