Rifle Zeroing.....

[PJWmids 35]

When you zero a rifle say at 25 yards on a specific magnification, does altering that magnification then change the point of impact slightly at the same distance, or does it make no difference once zero'd.

I wouldn't think it would make a difference, only difference would be if using the milldots. May be wrong.

no difference to point of impact mate, regardless of variation on the magnification, the only thing that will change if you turn up the magnification is the target will look twice as big and you'll see your heartbeat and any other movement increased, but if its zeroed at 25 yds, then thats where it will stay zeroed, in my limited experience.

 

hope it helps

It shouldnt make any difference at all. Unless you have a crap scope.

Yeah 4x and 16x *should* be the same at 25 yards mate

thanks

The hold over will change at ranges though if you keep changing the magnification but P.O.I will remain at 25 yards

As said, zero is zero. Won't change.

 

Your Mildot values at other ranges will change depending on magnification however, makes sense as the size of your mil dots relative to target either increase or decrease depending on the mag,

The mildot values will change at ALL ranges, including zero range, if you change the magnification setting from whatever it was when you zeroed and calibrated. The centre crosshair will be unaffected as your POI at zero range whatever magnification your on.

My above reply is assuming you have a scope with the reticle on the second focal plane. If you have a first focal plane scope the reticle will also get bigger and smaller as you change the mag, so the mildot values stay the same.

This is always handy to know, so thanks for the thread and the replies.

theres a first focal plane and a second focal plane thing, one changes the dot spaceing the other does not.

 

but in short the poi shouldnt change with mag change or parralex change. its a iffy scope if the poi moves.

 

eather way the zero point should always be there no mater where the focal plane is for the ret.

just had this argument with my mate so we tested the theory and all the above replys are correct as was I with my mate haha
