I'm curious what the dimensional difference is with a 0moa rail and 20moa rail, (for that matter 10moa, 15moa, 30, 40)? Will it be different for long and short actions? Is it an exact measure or a ballpark figure?(In some cases only getting 18 instead of 20moa...)

Do not complicate it unnecessarily; order the cant you need for the action you have. All of my rails thus far have indicated the degree of cant they are designed for.

I went through this last year . I thought I had a 20 rail , but my scope turret was about perfectly centered making me think I must have a 0 rail . it turned out I did have a 20 rail , but needed a 40 to get a 20 moa correction . in the link provided , the guys talk rail length and such . from what I figured rough and dirty , a 20 moa rail will be about .020" different in height . I have since bedded a few rails and added , or removed a little cant . there is more to this than just the cant in the rail , the position the barrel is clocked at will effect this .

How to measure on MOA picatinny rail?
I just bought a Savage FCP HS precision Lapua. I have read people commenting on differences in what rails came on their rifles. Im relatively new to this and do not know how to determine if the factory rail is 0MOA or 20 MOA. Can anyone explain how to tell the difference? Can I just measure the...

Basic trig. If you know the rail length, I can tell you the height difference (back-front) for each angle.
