Night Vision Simrad kn203 zeroing methods

[Ncloud]

Looking for your preferred process to zero Simrad kn203.

also what is the offset/ shift of your scope zero to when the simrad is in use.

I’m loaning mine out to a friend to hunt and I won’t have a lot of time to show him how to use it.

thanks

I use two types of mounts.
spuhr with a simrad Mount
And
Badger simrad rings

if its 203 zero it with your poi exactly 3.75" lower than you poa. after that I simply dial 1 mil on the day optic and you have a 100yd zero and mpbz to whatever your day dope is at 1mil. typically 300yd or so on most calibers.

per page 2-7 of the simrad manual, the kn203 POI should be 3.75 below the POA.

So the procedure is

01 - Zero your weapon at 100yds (91 meters)

02 - Mount the 203

03 - Fire a 3 rd group

04 - Adjust the 203 adjustment knobs so that the center of your group is 3.75 inches below the point of aim.

05 - bonus step, in my case, I fire another 3 rd group to confirm POI is 3.75 inches below POA.

+1 on Killswitch's method with a little twist. I dial up 1mil and zero dead on at 100. Then add 3.75" to the height over bore in the ballistics solver, and use pure holds all the way out with a Tremor 3 reticle.

So if we are supposed to be parallel zeroed between the POI impact 3.75 below and the day scope. Then we should be 3.75 low all the way out to infinity, right ??

So dialing the 1 mil gets us almost dead on for 100yds and in the ball park out a ways ... but 3.75 inches is not a good approximation of 1 mil out at say 600 yards, right ?

3.75” is about 1 mil at 100m. At 200 it would be half that (~1.8 mil), at 400 it would be 1/4 of that (~.9 mil) etc.

Easiest thing for me is to zero ~ 3.75” low at 100, use my normal dope and hold what looks to be about 4” high at any distance. No math involved and gets close enough for anything practical.

Thanks for the information

The second half of what sneaky posted is basically what I do as well, it works great. If you want to take time to dial each solution in the dark, be my guest, but MOA or mil reticle are perfect for this application.
