Rossi 22 ejection issues

[philpilon_97]

looking for any ideas on what could be causing some issues with my rossi model 62 pump 22LR. I recently inherited this rifle which belonged to my late grandfather. When I got it, it was in no condition to fire. Needed a new extractor, sight elevator and carrier lever spring all of which i replaced with parts purchased from homestead in Arizona. the parts were listed as winchester 62 parts but claimed to be compatible with rossi 62. After a trip to the range the rifle cycle and shoot alright, not the smoothest (bolt required some force to close on a chambered round, guessing it might be due to the extractor, from my research seems the winchester ones are slightly thicker than the original rossi one so probably is causing some resistance).

But the real issue comes when i reach the last round in the mag. For some reason the carrier wont lower after firing the last round and the spent casing goes back into the carrier. In order to unload i am having to force the carrier down while closing the action and then i have to shake the spent casing free via the tube mag. Just trying to figure out why this is only happening on the last round and if theres a fix?

The bolt and the lifter/carrier, cannot occupy the same space, so the carrier has to be moving down when the bolt is closed. Both the cam surface on the bolt, and the hammer, should be physically pushing the carrier down.

I would suggest that the first place to start, is to square away the hard closing issue, and to check carefully that the force used to close the action has not displaced any metal around the extractor cut on the bolt or the chamber, and that there are not any bent parts. Then look really close at the rest of the parts you changed.

Then start looking pretty close at the rest of the lifter, etc, looking for broken or damaged surfaces.
May very well be that the damaged parts you replaced, were a symptom, rather than the actual original problem.

Pay attention to the surfaces at the rear of the step of the bolt, these are the ones responsible for raising the carrier, on the back stroke. Also look closely at the Left side on the bottom, as well as where that point meets on the carrier lift lever, as that is what is supposed to push the carrier down on the fore stroke. The arrangement of the bolt, the extractor, and the carrier, should be preventing the carrier from rising until the bolt is clear with it's empty case. The extractor SHOULD be preventing the carrier from rising until it clears the rear notch in the bolt.

And I'll ask. Do you count rounds and set the hammer on half #### before you eject the last round, or do you run dry to a click? Because if the former, that might explain the difference on the last round. Just a guess. But even at that, something isn't right. Just gotta work through it methodically. Might be well worth the time to pull the bolt right out and sit and see how the parts fit together as you move them around where they are supposed to be, if that will help you visualize whats going on.
