How many inches will the SS crosshairs cover at 500 and 1000 Yards? Does it change with different powers? Will the variable's change with yardage changes?

 

Thank you.

IIRC it's one tenth mil and all the ss scopes are fixed power.

1 mil is 3.438 moa so -.3438 moa per 100 yards or;
1.047 (moa) X 0.3438= 0.3599586 inches per 100 yards

If you do it in a first focal plane variable the equation is the same.

In a second plane reticle subtension becomes a linear function of magnification and that sucks because you don't really know if 8x is really 8x or  7.88x or 8.123x so it only counts where the  INDIVIDUAL scope is columnated which means never ever buy a second plane scope if you really really want to use mildots for anything other than a fashion statement.

Thusly we conclude todays lesson in the finer points of not much whatsoever

Mike,

 

It looks like about 4 tenths of an inch@100 so that means about 4 inches @ 1000 if my math is correct. If I remember right the X ring at 1000 is 10". I read where one poster said the SS reticle covered the X ring at 1000 which wasn't quite true.

 

I was looking ahead to the SS variable coming out. So it sounds like the Mil would be set at one power anyhow.

 

There was a book out that was supposed to explain everything about how a scope worked, which I will try to locate. Different focal planes, recticles etched on glass etc. are new to me. I've learned some new things on this and a few other sights.

 

Thanks. Bob
