Zeiss LRP S5 3-18x50mm Field Eval

[Formidilosus]

This is a field evaluation of the Zeiss LRP 3-18x50mm scope (actual magnification is 3.6-18x). This scope was brought to me from Ryan Avery for an evaluation. The ammunition used was Hornady ELD-M Match 168gr that was purchased by Ryan. The 20 round proof group was just over 1.1 MOA.


The scope and weight-





Turrets:


Elevation turret is exposed, revolution indicated, 12 mils per rev, and zero stopped. Zero stop requires a tool. Windage is exposed and locking by pull up/push down.


Elevation-








Windage-







ZF-MRi Reticle:

3.6x





18x





Red illumination on highest setting 3.6x-





On 18x-





The reticle is similar to most other .2 mil tree reticles.

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, failures in actual use are almost unheard of.

This one was conducted on soft dirt/mud with a 1/2” padded mat.


Zero Target-



After boresight, the first round was high on center dot, read the reticle and adjusted down. The next five were left dot- it did not adjust as it should have. Adjusted again, and ten on the right dot- again the error in the movement seemed larger than it should have been.

Drop eval-




First shot was a confirm Pre drop. The rest is as written. Clear shifts from 36”, and the 3x3 36” drops put it totally off the paper. After putting other targets up to see how much, it came out to an 8.5 mil (30.6 inch) shift.






At this point it needed to be remounted, and the rings (Zeiss) were suspect. That would have to wait a bit. In the meantime the scope was remounted and rezeroed. Over the course of two months, it got shot a bit, lost zero up to 1 mil, and had to be rezeroed a couple of times- all just from riding in a padded seat.

Even though it didn’t look good, the scope was remounted in some very solid rings as the eval redone.




Zeroing-


BS was left of center dot. Read reticle and adjusted right. Next ten was in center dot and it again was being weird. It would hold impacts in the general expected cone, then jump for a shot or two, then come back, then jump for no reason. The only total cone was twice as big as it should be.



Drop eval-

This eval was conducted on relatively soft dirt, on over 1 inch of padding.




The first shot was a confirmation and was off again high right. A second shot was fired and it hit the dot. Then the drop eval started. The 18” went ok, the first 36” on the left side shifted .4mils. The second 36” drop on the right was different all together….











Well…..
