Seems I remember reading that ER is extended at the expense of FOV, a function of optical engineering.

I recall Bushnell coming out with their 6500 1.25-8x32, a 30mm, 15.8 oz DG type scope. As I recall, Dom (writing frog) was very critical of this scope. Bushnell specs said 6" ER, some write ups used a 5" ER value. At 1.25X, the FOV is 60'. A VX-6 1-6 has a low power FOV of 116', even the VX-6 2-12 has a low power FOV of 57'.

1.25X isn't that far from 1X, but the comparitive FOV is almost half the VX-6. So, for the extra 1" (or 2") ER, they gave up a bunch of FOV, which is an important consideration in a DG type scope.

Apparently the 6500 1.25-8x32 was not that well received.
