I have used the 1.4-4.5x32 wide angle Banner on my NEF 30-30 barrel to drop 2 deer, both at 75 yds and a fox at 40 yds.
A kid used it to drop a bobcat at 65 yards.
It has a 50 yd parallax, which you only notice at the range.
Had it on a 22 but the crosshairs are kind of thick for 22 shooting.
I also have 4-12xAO and 6-24AO Banners
