If your red dot isn't hitting where you aim, then it isn't sighted in correctly.  If it's sighted in correctly and still hitting low, then it's the operator.

This.

Man speaks the truth.

If you sight in your shotgun for a 25 yd zero, anything closer than 25 yards will begin to hit below zero. This is because your line of sight will need to intersect your line of projectile flight, by dialing your sight downwards. Therefore, the closer the target is to you under 25 yards, the higher you will need to aim. On the other hand, anything past 25 yards, you will begin to hit high, and you will need to compensate higher until gravity takes over and the projectile will pass back over zero again at some point. All projectiles are different. See the picture. This is the case with all sights, irons or optics. This scenario doesn't apply to beads on your rail, because your line of sight using the bead is basically the line of flight of your projectile.

The red dot could also be defective....although not likely.

Two shots and two dead birds I don't see the issue? Sight radius between the barrel and red dot on a low mount is less than 2" and we are talking about a scatter gun not a rifle. A 10-20" Pattern should be more than enough to compensate for a 1-2" variation in poi between 15-40 yards. A shotgun is not a rifle, poi changes because the wad floats, drifts, opens differently, and moves around from shot to shot. Not much but 2-6" at 40 yards between shots is typical. Again haven't a 15" pattern negates this making it a non issue. Birds move, poi moves, shooters POA, lots of variables.

Spot on!  I sling turkey loads at way more paper than I do at turkeys and can vouch for the variability in POI. That goes for even when you are controlling for variables like temp, wind, barrel cleanliness, gun, load, shooter, rest...

Sight in at 12.5 yards to make sure POA/POI are dead on.  This will give you a nice hole to adjust to and since most red dots are 1/2 inch moa at 50 yards, you will have 1/16th inch adjustments at 12.5 yards
