Calculator was rigth. 3/4ish high at 50, on at 75. Which will put around 1.5 low at 100. Haven't tested it yet. Nice thing is 38-45 grains POI was the same, at 50 yards. Maybe with hig speed rounds at such close ranges it would be too. But sight in with powder puff 1500 FPS, hunting around 1700. Which is over kill probably.
You got to check screws though. They come loose. Put some loctite on them. I don't typically do that, but it opened up while shooting.
