I have used the NXS 2.5-10x24 mounted in 30mm LOW mounts on both 308 and 6.5 Creedmoor and I cannot remember one failure to eject.

The 308 I fired extensively from a bench and in some hot-and-heavy South Texas hunting.

The Creed was all on a flat range from the bench and various unsupported positions.

Runs like a top.
