How would zeroing at 100 and then shooting at 500 change how much elevation I need to get there?
Im zeroing at 500 because my back stop at 500 can handle a 50 cal round.
 
yup, doesn't matter what distance you zero at but He has a point about a 100 meter zero. Either way you still have the same usable elevation in your scope guts. Did you bypass your zero stop or not?
 
What do you mean zero stop, thought that was a night force thing. When I put the scope on the mount and zeroed it it took 11 mils of elevation. Then I sliped the rings hoping to gain a little bit more elevation, and now my max elevation adjustment is 16.5 mills, from zero with a 500 yard zero.
 
give me a minute, I'll find a good link for you.

Confirm with your owners manual from s&b as it has different instructions for different turrets but the theory applies to double turn turrets despite external appearance

Even if I repeat myself

load a picture of the set-up

after that all of us will be able to help

I had the same problem with a US Scope and a Cadex stock 20 MOA problems problems...

For some reason I can't see the pic but your 45 moa mount should gain you 13 mils of up, and if it's set up properly the only thing I can think of is that your zero stop post described in the link is not in the right position.

Actualy I think I was able to gain 3.5 mils of elevation. So now im siting with 19mill of travel, from my 500 yard zero. I think running the h37 retical will cost 4mills of evevation, becauses the zero point is 4 mills higher. And im lossing some adjudtment because im zeroing at 500. I will check everything out next sunday to confirm everything and post how it goes.
Thanks everyone for your input.
 
If I can add to the discussion,

Sometimes, scope mounts even from AI are stamped with 45 MOA add it happens that the final spacer is missing.

Please, try the following procedure.

Using your caliper
measure the distance between the scope ring (outer dimension), this will give you the base of the triangle;
measure the height from the bottom of the scope mount up to where the scope rest on the ring, this will give you the first height (near your eyes);
measure the height of the other ring, this is giving you the second height where the scope rest on the ring.(towards the end of the barrel)

Substract these two height, you have now the ELEVATION of you scope mount. (first height should be less than second height)

the Angle is obtain by simple trigonometry.

If you provide us with these dimensions we will compute the MOA for you.

Regards

should be roughly .8 of a mm difference from front to back of the mount IIRC for 45MOA. If after all of this you still cant get the elevation out of it...get a 70MOA mount lol.
 
Yes I did do that yesterday and I got the mount to be 45.3 moa. Close enough for me. My mesuring was probaly off because I did not want to take the scope out of the rings.
