I am currently using a Leupold EFR 8-20x40 on my BSA for Mini-McQueen.

Getting as high a magnification as possible so you can see the tiny v-bull makes it easier BUT you cannot go so high as to not be able to see the whole castle !

On the Leupold, I can use 20x and see the whole castle.

Now, I assumed with a bigger objective such as the 56mm on a Nightforce ( and the bigger 30mm tube ) one might get a little more magnification while still getting a decent FOV ?

But amazingly, you can only use up to 18x and still see the castle fully.

So, have any of you come across any scopes with lots of FOV at higher magnification ?

Hi Breacher

I have been looking at scopes for a future purchase and one review I found online went in to a fantastic amount of detail about the scopes he tested. It is a little old (2014) but it could be useful due to one of the metrics he measured.

In the overall optical performance chart, the blue bar (field of view points), tells you what can be seen at x18 on the scopes. The Kahles 6-24x56 seems to have the widest field of view from what he measured. There does not seem to be a direct correlation between objective lens and field of view, I would guess it is affected by tube size, zoom range and the overall design as well. I am guessing that the widest view at x18 will still be true at higher magnifications, thus allowing you to zoom further in, as you want to, while maintaining the minimum field of view required. It may give you a starting point as to which scope to short list and go to look through at least.

Thanks Matt.

I found that when googling.

As far as I can make out from looking around - I am already doing quite well with FOV ! Which is a total accident as I just wanted a decent scope which focused from 20 yards out to longer ranges too and just happened to gt one with decent FOV.

Normally the longer focal length you go with a lens (higher mag) the narrower the FOV. The objective size has more to do with light capture as does coating.

I shoot the McQueen with a March bowl-32x52mm and the maximum zoom I can use and still see the whole castle is 20x.

As I can see the V bull and my bullet holes, I would say it's adequate!

I believe that eye relief has some bearing on FOV too. My Connect 01 has very, very short eye relief but enormous FOV.

I shot the McQueen on Saturday and for the first time ever I noticed my bullet holes; slightly off putting as 3 of them were in the 4 ring!
(S&B 3~20x50 on 18x mag)

I thought the early morning light on Saturday was the best I'd seen on SS.
