The Ranch did not "lack" an ejector- that would be impossible...
Style was changed, from plunger type to a fixed ejector- and yep, it throws brass halfway down the firing line.
When you're getting thunked in the head by flying brass at the range, look twenty or thirty feet in that direction, you'll find the Mini...
The ejector change also affected the angle of ejection, the Mini would eject more vertically, banging the scope...it was changed to eject at a lower angle to miss the scope.
If you plan on scoping, sell it and buy a Ranch (the new models since Ruger re-tooled are far more accurate), but they're fine for shooting with the irons.
