Hey everyone.

I have 2 SB 3-12x50 PMII

Both are looks the same different stamp on tube.

Both mounted on the same rifle .
Bolt , 308 , 20 MOA base

The second one , I can't zero the scope at 100 yards.

Any thoughts?
 
Is the error large or small?

There’s no side focus on the 3-12 PMII if I recall — do you know from the literature what the factory parallax distance is? My guess is it’s likely 200 or 300m.

If the error is small I wonder if it’s a parallax problem, that arises from using 12X to zero the scope at 100 yds?
Maybe try again using lower magnification — say 6X — and see what happens.

With lower magnification I can see easily shoots below than bullseye almost 3 inches at 100

I'm going to try zero the rifle at 200 meters
