Does anyone know the subtensions for the Zeiss RZ-800 reticle? Preferably in MOA. I found this old post but the images are no longer viewable.


I know this is a little dated reticle but the glass is nice and it makes for a great medium range hunting scope.

Thanks!

It sounds like you already have the scope, correct? If so why not set up an MOA target at 100 yards and measure with your reticle?
Yes I do but the lines in the reticle are on the thick side (0.35" I believe) which opens it up to some error.

I just figured it would be easier to find the data if it was already published.
 
You Google Fu is weak my son. The answers are right on this very board.



Zeiss Ballistic Calculator. You can reverse calculate the inches per mark.

There is no answer to your question because the holdovers change depending on all sorts of factors. There are only two ways to know what they are.

1. Become a master ballistician/mathematics wizard. OR
2. Download the zeiss app and enter in the data it wants to use to calculate the exact yardages for each holdover in the given elevation, temperature, bullet choice, bullet speed, etc... in which you plan to lob said bullet down range.
 
Here are screenshots of the app. Notice how the magnification setting changes the holdover subtensions. The preferred magnification level of 9 changes to give you the closest number to match each holdover line x 100 yards.

Other screenshots of the app for my 338 win mag. You can set up multiple profiles if you are a scope-switcher or have multiple zeiss products. I am not a scope switcher.

Thank you for all the info. This is great info for the RZ7 and RZ5 reticles. I'm not sure if the same subtensions would apply to the RZ800?

I joined and used the Zeiss ballistic calculator and that gave me some good data.

Thank you. I joined their app and yes, it does provide some very useful data. I'll play with it some more to fine tune it, but thank you.
 
I know I see MOA subtension data from other manufacturers. Not MOA data of bullet POI but of reticle hatch marks. I shoot a lot of Leupold scopes as well and I know MOA reticle data for each of them as provided by Leupold. Here's an example for their Boone and Crocket reticle which is similar to the Zeiss RZ800 reticle. At full power here are the hatch mark MOA subtensions. I don't know why Zeiss doesn't have something similar? In my head I'm thinking they must have this data but it sure isn't easy to find. Thanks for all the replies!

Might be worthwhile sending the Leupold example to Zeiss and ask them to publish something similar. It may be that no one ever asked and they didn't think about it for the newer scopes, given how prevalent electronic calculators have become. At minimum I bet they at lease send you the Z-800 info.
