Post by OvenpaaFirst post and it has to be a question. I have just acquired a S&B 4-16X50
PMII with the P1 Bryant reticule (thanks wife!) - this is a metric scope so
one click = one cm.
My question is how does this work - how can I relate this to a target, I
vaguely understand MOA but not cms, is it at a set distance or based on the
reticule size at a set magnification or something else?
Presumably, 1 click equals 1cm at 100 metres?
Typical imperial scopes are 1/4 inch or 1/8 inch at 100 yard.
I'm not sure about this scope, but some are only true at certain zoom
ranges - say, 10x zoom is the only point when 1 click = 1cm. You need to
read the docs to find out if it is true of the full zoom range or at one
mag.
So, if you zero the scope at 100 metres, then turn the top (elevation)
turret clockwise(all scopes I have had work this way round, though
others may move the point higher) by 1 click, the bullet will now impact
the target 1 cm lower.
1 cm seems rather a large movement, better scopes tend to have finer
adjustments, 1/8inch equals around 3mm, so are you sure it is 1cm?
The side movement will also move by the same amount with 1 click.
If you know the distance correctly that you are aiming at, then it is
easy to set up the scope initially, e.g., if you are (if in fact it is
1cm at 100 metres) 4 cms high, and 6 cms right, then you do 4 click down
and 6 clciks across, and the next bullet should be dead on target.
Then, once you have the zero set correctly, you need to find out where
the rifle is shooting at different distances.
So, say you want to shoot at 200 metres, (and asssuming there is
negligible drop of the bullet during its flight), 1 click will move the
reticule by 2 cms. At 50m it will be .5cm and so on.
In the real world, a bullet will have dropped a little in its flight at
200 m, and will be a little higher at 50m than at 100m, so you need to
test all all ranges you are likely to be firing at.
