16 inch barrel

I just sighted her in at 50 yards. At the 100 yard range my POI is 1.5 inches higher.

What will be the elevation at 200?

Go to Hornady's ballistics calculator and use 175 yds for the zero. It matches up pretty well with the numbers you have given and puts POI at 1.5" low at 200 yds. The bullet has a BC of .400 and muzzle velocity of 2460 from a 16" barrel.

I figured out the calculator but your sight height must be TALL. Even at 2.5" of sight height and 50 yd zero, it said 100 should be .9" high and that would end up 2.5" low at 200.

The best way would be to shoot at 200 yards for an accurate figure.

Yes my red dot is sitting on a larue660T so it is up. I wanted to shoot at the 200 yard range but it was pouring down on me at the 100 so I left early. Couldnt even get pics of my range session.
