Scope Magnification Questions.

Me and my encore buddy were at the range last night and We came up with what I though were good questions. Basically I just would like to know what makes a 10x scope a 10x scope. At what distance do they base this on? Obviously its not 100 yards, but is it 1 foot? 1 meter?
And can anyone reccomend a good site for properly setting up a scope? And how to know its properly set up? Thanks in advance
 
magnification has nothing to do with distance. Magnification is a simple function of focal length of the objective divided by the focal length of the eyepiece. A variable power scope works by changing the focal length of the eyepiece, and hence the magnification.

Viewing something at 10x will make it appear 10 times larger than with the naked eye, whether the object is 1 foot or 1 mile away from you.

I don't understand exactly what you're trying to ask regarding the distance?
 
Okay. If I have a ten power scope, and I look at a 1 inch dot. At 100 yards the dot does not appear to be a ten inch dot (x10, right?). But, there is a distance where the one inch dot will appear to be a ten inch dot. Is this distance an industry standard? If so, what is the distance?

And if Im totally off base, where the heck do they derive there version of what "x" actually is.

Im goin off the fact that I have a weaver K10, and an older leupold 10 power, and my buddy has a bushnell 4x12 (set on 10x).
Each scope when focused on a 1 inch dot at 100 yards gives a
different picture. The weaver and the K10 were similar in quality, but both were noticabley different, and the bushnell was just out of its league.

Im just tryin to figure out why.
 
The distance that the dot appears to be a full 1" is the distance that it will subtend 10" in your scope (in theory).
Actually scope makers use math formulae to determine the power.
Bushnell is often out of it's league
 
If you put a 1" dot at 100yds, and a 10" dot at 100yds, and look at the 1" dot through the scope, it will look the same size as the 10" dot with the naked eye.

Where is the problem understanding this - it has nothing to do with distance.

No mater what the distance... an object looked at through the scope will appear TEN TIMES AS BIG.
 
If you have a one inch dot at 200 yards and a pie plate at 100 yards the scope will still be the same size. /ubbthreads/images/graemlins/grinning-smiley-006.gif But if you have a passenger side mirror from an '87 Buick the object in the mirror will appear closer than it really is. So if you are looking at the pie plate in the mirror it will appear to be 50 yards away not 100, still it's larger than the dot at 200 yards.

Good answer, I could not have explained it better myself. /ubbthreads/images/graemlins/laugh.gif

See thats the thing. To me it doesnt, it looks smaller. Not trying to come off as a numbnut. But I would figure targets would be larger than what they are appearing.
