stupid question...

I have a nikon prostaff 4-12 X 40 on my AR and a Nilon Monarch 3-12 X 42 on my browning.  Today I had them both at the range and maxed out at 12 times but the target looked MUCH bigger on the 4-12 prostaff.  Can anyone tell me why?????  Thanks

What's the eye relief on the scopes? Your eye may have been closer to the scope, and everything is bigger when its up close...
Was the Monarch mounted backwards?
eye relief is about the same for both scopes.  The monarch is mounted properly.
The other possibility is 42mm scope has a larger exit pupil measurement a .5mm makes a difference to the eye.
the prostaff has a FOV (field of veiw) of 7.3 ft at 100 yards at max zoom
the monarch has FOV of 8.4 ft at max at 100 yards

SO! because the image area is bigger on the monarch, the target appears smaller, even though the target image will be the same relative size at 12x

Bingo! Couldn't have said it better.
