parallax

[pedro68 3]

i have a Hawke nite eye 3x12x50 AO scope and would like to know how i adjust the parallax and what range is best for air rifles . any advice would be great.

HI peter,

 

AO means Adjustable Objective.

The Objective is the front lens on the scope. There will be a grip with a dial and range markings on the front end. Simply turn it to the required distance

 

I have mine set at 35 yards, but I alter it to the distance that I am shooting at(if there is time)

Just to add parallax adjustment is more important on a scope with a larger front lens due to depth of field is better the smaller the front lense.

So it's a pay off between light gathering and depth of field.

And it's the depth of field that allows you to range find at a high magnification.

If your target is x yards away, simply turn the paralax adjustment until the target is in clear focus, then read off the yards on the indicator and thats howfar away your target is. The higher the mag,the more precise the focus, the more accurate the yardage

hi there , thanks for the replys, phantom its an s200 im shooting and basically bought the gun as its recommended for accuracy ,when i zero the gun at say 30 yards and then when i shoot at say 10 yards the pellet hits 3 or 4 mm to the left, is this due to parallax. iv not got a clue about this to be honest , i was using the focus at the front of the scope basically toget the clearest image ,but the yardage on the scope is not strictly correct as it may read different to the actual distance , does this matter. sorry for questions , but i thought there was a way to adjust this .

Hi Peter,

In short to answer your question, yes it could well be.

As scopes are mass produced, they may not always be spot on. My Hawke HD scope is not spot on, but my Leupold MK4 is (But thats a sidewheel parallax and manufactured to exceptional standards).

What I would suggest you do is cut out little lables using either meters or yards from say 10 out to 50. Then either using a tape measure or LRF place targets at each distance you have made a lable for.

Then at say 10x mag, focus in the nearest target. When its in focus, pop the 10yard/mtr lable on the top of the scope ring. Repeat the process for all the other known distances and then you will have an accurate range on your scope ring.

 

Hope that helps a little

Hi there ,im going to set the parallax at say 40 yards and zero at 35 , then i iwill do as you say and try it at all the various ranges. hopefully it will be cured and i will again trust it to put the pellet where i want it.

 

cheers

One thing you can try is to accurately measure out the ranges; 5 to 50 metres say, in 5-metre increments with a tape and set your scope to focus as sharply as you can on each one and mark it on your scope focus ring. I use a fine brush of Humbrol enamel light grey and a masking taped, very fine strip-line, defined by two edges of masking tape, on the mark.

 

Voila! Instant range finding and paralax setting!
