That bullet and velocity should shoot pretty flat out to 150 yds!

Is parallax coming into play?

[JEBar]

per our ballistics program with a Nosler 150 gr Ballistic Tip bullet your bullets trajectory when zeroed at 100 yards would be as shown below

Calculated Table
Range
(yd) (in)
0 -1.5
50 -0.2
75 0.1
100 -0.0
125 -0.4
175 -2.2
200 -3.6

What does it say if zeroed at 25 yards?

Thanks. I’m thinking parallax at 25 yards for a centerfire scope might be playing a part. Just a guess.

[JEBar]

hadn't considered that .... if he fires it using the iron sights and it is close, that eliminates the rifle and leaves the scope as the problem

And/or scope shadow.

[cityhunter]

No shadow was in the scope. Checked and found that Scope is designed for
Parallax Setting 50 yards
It is Diamondback 2-7 X 35
Can that play a role??
