Yes. I was having constant (~50%) ejection issues on my 6.5x47 built on a stiller tac30 with a gen 2 razor in a spuhr.
I made a slow-motion video of a bunch of cases attempting to eject, and found that basically every single case hit the underside of the spuhr. Half the time, the case would hit the mount and very barely eject into a pile basically below my action, and the other half would hit the mount and fall right back into the action.
Hadn't considered that it would have been a left hand only thing but it makes sense.
Got rid of the mount because of this, and replaced with a set of PMRs. Have had zero issues since.
