Hello Everyone: I currently have my EO Tech zeroed for point of impact out to 50 yards. This seems to be popular way to zero the sight for many distances out to 200 yards. However, I am finding that with this method that the point of impact is low at 75 and 50 feet. I don't believe that I will do any shooting out past 100 yards. Is there a better zero method effective out to 100 yards that will raise the point of impact at 50 and 75 feet? Thank you!

| Hmmm, I have mine zeroed at 50 yrds and find that it only shoots low the closer I get. It shoots high the farther out I get. The difference is inches and easy to compensate. Not sure what to tell ya. A rifle zeroed at 50 yards should be accurate out to 300 yards or so. This is my duty patrol rifle so accuracy is important. |
Thats correct and its all going to be a compromise within that distance. The bullet is not traveling flat out to 100 yards, so no matter where you zero at, it will be high or low somewhere along that line. The flight of the bullet is rising all the way out through 100 yards. So if you sight anywhere between 0 and 100 yards, anything closer the bullet will be low and anything further than your sighting distance impact will be high. Thats just how the physics work. So if you sight at 50 yards, anything less than 50 will impact low and anything past 50 out through the 100 yard mark will impact high. Nothing you can do about it except know how to compensate for it and use hold-overs and hold-unders to shoot accurately. |

Unfortunately there is no "perfect" zero for the varied distances you described. If you want to be POA = POI at the closer distances you mentioned, you'd be better served with a scope with elevation adjustment settings. If you want to stay with the EoTech you need to pick whichever zero is closest to the distance you'll be doing the majority of your shooting from and then learn your hold-overs (as mentioned above.)
