I just acquired a new, old Savage M-219 singleshot in .22 Hornet. While I had it apart to clean out the dried oil I snapped a picture of the extractor/ejector parts. It is basically like the H&R but with a significant difference.
The ejector latch has an arm sticking out to the left, toward the camera, which engages a shelf in the frame, just like H&R, but it is pivoted at its front end, unlike H&R. The ejector spring also powers the latch by pushing forward on the upright leg of the latch.
As the gun is closed, the extractor is pushed forward, compressing the coil spring until at last the latch snaps into the forward notch of the extractor.
As the gun is opened, the latch hits the frame shelf and disengages from the extractor, allowing the spring to drive it rearward to eject the case, just like H&R. But here is that significant difference. If the case is stuck and the spring alone cannot move it, then as the gun opens farther that upright leg of the latch first adds more compression to the spring and finally the rod inside the spring will contact the front end of the extractor and force the primary extraction. The H&R ejector has no primary extraction, just a spring.
The Savage's primary extraction alone will move the case only about 1/16" but that is enough to break it lose so that the spring can then drive the extractor to its limit and eject the case.
I always replace the factory ejector spring with a much lighter spring as pictured. That makes the gun much easier to close and will still throw the case clear of the gun, just not clear of the county.
