I am having issues with my IOR terminator elevation, need help please

my manual tells me I have 100 moa elevation and I can not get anymore than 64 moa elevation. Any ideas what I am doing wrong ?
A scope having 100 MOA total elevation means from the very bottom of the rotations to the very top. You actually zero with a rifle and some fired rounds is going to be at least in the middle, possibly a little above it. Which means, after zeroing, you will have less than 100 MOA to adjust before hitting the top. If you have zero stop, it depends on the style of zero stop. Arkens have a zero stop that is good and lets you run to the top of the turret rotation.

Some Vortex scopes have a Rev Stop ring for zero stop and that allows 2 full rotations before stopping. Which can still be good, depending on what cant of rail you have on. For example, long range shooters and some long range hunters are often putting on a 20 MOA rail and zeroing at 200 yards, which gets back some the MOA or Mils that you may want.
 
This is my setup: - scope has 100 moa from bottom to top. I have a 20 moa rail on the rifle. zero stop removed. I thought by putting on a 20 moa rail it would allow me to zero at 100y

Thank you very much for your help, ill look into this now.
 
half scope travel is 50moa

20moa cant gives ~70 usable

the 6moa difference is getting your zero. hence 64moa

you can run 40moa of cant and get another 20moa of travel safety and still zero at 100y though you may have image degradation low in the travel depending on the scope

example. vortex strike eagle have 31mil travel. i can run 60moa of cant (17.4mil) travel and zero my rimx at 25/37/50y.
 
do you have your scope rail on back wards ? maybe pop did that with our crusader and ended up zeroing it at 100 yards only to have near nothing left to go further , you might also want to look into a 30moa scope rail .
 
Doesn’t that scope have some type of double zero stop so that it can be setup with two different rifles?

Edit: ok I looked it up does it have two different POI settings for the zero stop?

Still zero at 100. I zero at 100 with 40 or 60moa of cant

You're using the same elevation either way whether you zero at 200y or dial it from a 100y...you have to account for the drop somehow...a measly half mil at most anyways
