I can't believe all this agro here I'm bringing out the picture then!!!!!

Information replies left, deleted all the purely argumentative posts.

Hopefully Sally is satisfied with the answer and we can leave this now...

I have just been supplied the figures for a .223 with a 55 grainer at 200m

With the scope mounted 1.5" over the boreline the cant error at 5 degrees(whatr the average person still thinks is level) is 19mm windage either left or right depending on the hold and 16mm drop. (total possible group windage error-in addition to the rifles inherent accuracy- 40mm)

When you raise the scope to 2" above the bore line windage increases to 32mm error and 25mm drop (total possible group size increase of 64mm)error

So for 12mm increase in ring height you are blowing your groups out almost an extra inch at 200m.

Not insignificant, I wasn't expecting it to be as much as that but ballistics programs don't lie apparently(I am sure they do, this wasn't my program so if anyone wants to do the math feel free), some people would spend a lot of money trying to eliminate that amount of error but no one sensible would ignore it.

Keep rings as low as possible and try to shoot with a level rifle remembering that 5 degrees of cant is usually undetectable by the average person.

I'll take your word for it.

Wouldn't know where to start on checking the math
