I have a used fox scope it came wth no instructions
Quick questions
It says 1/8 per click what magnification is that? I'm guessing it has to be at a certain mag setting.
Say zero my scope at 100 how many clicks do I need to move to adjust for 300 and then 600?

1/8 per click will be at 100yrd range...so at 300yrd a click will equate to 3x that & at 600yrd a click will be 6x that: i.e. at 800yrd a click will be 1"

The number of clicks required will be down to the weight of bullet, muzzle velocity and ballistic coefficient. Once you know these you can easily calculate the number of clicks/MOA required using something like JBM:

Back to basics... the "1/8" means it will move the crosshairs 1/8 of a minute of angle (MOA). As 1 MOA is roughly 1 inch at 100 yds, 1 click will move the point of impact (POI) 1/8 of an inch at 100 yds.
This does relate to distance...double the distance, double the movement.
So at 200 yds 1 click will move the POI 1/4 inch, at 400 yds it will move it 1/2 an inch, and as Saddler said, at 800 yds it will move it 1 inch.

Thanks guys
Ahhh 800 yards 1 inch all becomes clear makes sense wish listed in maths. She'd make these lessons at school might have paid attention.
Think I'll work all out and write it down I'll never remember numbers
I'll try the calculator too

Using tat caluculator I'm now confused again
So at 300 yard 10.9 in drop so I need to calculate (1/8 x 3) /10.9 yes?
Heads hurting now I'm going to go make some bullets rest my brain

Forget the inches bit, you are interested in the MOA and 8 clicks on your 'scope equals 1 MOA

Ok so if my maths is correct
100 yards 0 clicks @ 1 click is 1/8 of an moa
300 yards 9.3 Clicks @ ( 1/8 x3) / 3.5 ( 3.5 being Moa drop as per above table)
600 yards 15.7 clicks
800 yards 19.3 clicks as 1 click is 1 Mia @ 800 yards
As we can't do points ound up? Turning turret to raise bullet impact.

To be honest, i don't see the point of the 1/8th MOA scopes... I suppose if you're a benchrest type, that 1/8 of an inch at 100 yds may make a difference, but for most shooters 1/4 click is plenty fine enough adjustment.
No... don't forget you have 8 clicks per MOA......So for 800 yds, you need 19.3 MOA... at 8 clicks per MOA thats 154 clicks... good luck counting those out

Jesus it's like being back at school doing homework before a test I've even shown my working
That's enough brain Work for tonight I'll think about it some more tomorrow. Maths was never a strong point
