This is a field evaluation on the Zeiss V4 4-16x44mm MOA scope. Jake at @Unknown Munitions requested it from Zeiss for the eva.
The scope and weight:
Turrets:
External elevation, 20 MOA per rev, with zero stop and revolution indicated. Windage is capped, with a spring loaded dial- pull up, rotate to zero, release.
Reticle: ZMOAi-T30
It is an illuminated, MOA reticle.
Illuminated on setting 10/10-
Zeroing:
The 20 round proof group with Federal Gold Medal Match was 1.2” at 100 yards.
Went without issue. Boresight, adjust, next 7 rounds in left dot, adjust and slip turrets (elevation slipped when I was loosing the turret), next round low under top center dot, adjust and next three in the dot.
Drop Evaluation RTZ and “Tracking”:
For an explanation see- Scope Field Eval Explanation and Standards
The “test” consists of three 18” drops on a mat- one left/right/top with a shot to check zero after each drop. Then the exact same thing repeated from 36”. Then three drops on all three sides for nine drops on the last part- 15 drops total. This is not “abuse”. The 18” drops are a joke really. The 36” start showing something. And when a scope make/model consistently goes through the whole thing without losing zero, and makes it through the high round count portion, failures in actual use are almost unheard of.
This one was conducted on soft, semi packed soil.
It lost zero on the first 18” drops The 18” drops shifted POI around .5-.75 MOA. The 36” about 1 to 1.25 MOA.
Went back to zeroing target and shot 5 rounds-
Adjust zero and began the RTZ portion. No issue.
On to “tracking” (adjustment value). Used reticle to measure between top and bottom dot- 24.25 MOA, and proceeded to shoot it. No issues at all.
Conclusion:
It failed. It zeroed fine, adjustment values are correct, and return to zero is fine. However, it shifted zero from nearly every drop at both 18” and 36”. This V4 behaved as all prior versions that I have seen have- they are fine optically and in basic function- adjustment and RTZ, but are relatively fragile with impacts (especially left side and top).
