Rifle Scopes IOR Reticle Visible @ what magnification ,FFP

Re: IOR Reticle Visible @ what magnification ,FFP

I guess I didn't clearly state my question.

I was under the impression that since the size of the reticle increases in a FFP scope as you increase the magnification. Therefore the reticle will be quite small at lowest mag power on scope.

So with scope on lowest mag is reticle very small and barely visible. If that is the case then what mag on scope I reference above is needed for reticle to be easily visible?

I run an IOR 3-18x42.

Yes, the reticle appears smaller, you can still see it VERY clearly, but it appears to look almost like a standard crosshair, and that is the way I use it at low power.

Someone with better eyes might be able to clearly make out the hash marks, but I do not worry about it, if I am using 3 or 4 power, I am not ranging or shooting at a distance that requires leads.

OK so by 9 power you can see the hash marks pretty good. I do not have the great vision.

ronas,

the reticle in the 3-18x42mm when I designed it is to be used at all mag ranges. I have used the scope in question at 3x to do holds out to 600yds many times.

As a matter of fact, mine stay between 5x - 8x 90% of the time due to the FOV and reticle size.

as a note, the reticle does not get smaller per-say at lower mag

What happens is this, the reticle in all FFP optics sub-tend a unit of measure. The appearance if the reticle is directly related to the FOV. If you think of it this way:

A mil # 100yds is 3.6" So if the FOV is 27ft, the reticle looks bigger than if the FOV was 50ft. Due to 1 mil is covering 3.6"

So this is how a FFP optic works and keeps its size the same no matter the FOV adjustment, as you adjust the mag level of the optic.

On the other hand, a SFP scope, as you adjust up and down the mag levels, the reticle does not adjust to stay the same unit of measure. So the reticle looks to you and other shooters to not move, when it reality it is, and is getting out of whack for a lack of words.

No, 3" is 1/2 IPHY not .25 MOA.

If its a true MOA reticle then 1.57"

If its a IPHY then 1.5"

And also remember why you would buy a variable scope in the first place, you won't do ranging @3x as that's like catch22. What lower mags are great for is close quarters snapshots or hunting moving/real close animals. I think most of the time scope will/would be set somewhere between 10-18 depending on user preference and lower mags would be for rare occasions where one would need either big FOV (movers, battle etc...) or some really close (<200y) work.

Still on the new 3-18x50 i think illumination will be handy as you can use 3.5x and illuminate reticule and you have instant "red dot" sight...

Thanks to all who have answered my questions. They are most helpful as they allow me to understand much better what I will see as far as the reticle and how much of the target will be visible in FFP scope; on both high power and lower power.

Seems to me that reitcle is still usable for some ranging at 3x as the distance between the heavy stadia is 10 mils. So in the above picture I'd say the width of that tree trunk is 6.3" if the distance to it is known to be 35 yds. Right? Perfectly usable at 3x I'd say.
