Had one on a .30 Nosler - the telephone pole rifle in the Idaho moose hunt story in General Big Game.
Has about 200 round under it - dialed it for multiple trips past a 200 yard zero.
No issues, dials to what the drop chart and the weather apps say it should, returns to zero.
Optically - no issues with shadow or edge black, and haven't found a morning or evening that it wouldn't let me shoot past what was legal light.
Trying a 2.5-10 next, expecting similar results.
YMMV
