Re: problem with loading an 1884 trapdoor

Well, I suppose we have all been assuming your rifle is (as are the vast majority) in good mechanical order with all parts functioning.

With the block fully closed, you will note a small slot, with a lug towards the rear, just above and to the left of the block inscription. That lug is the upper part of the extractor, which is pivoted on the hinge pin. It is powered by a very strong spring located in a bored recess parallel to the chamber. When the block is opened to the vertical position, its' upper face contacts the lug and causes the extractor to rotate. The afore-mentioned spring - which normally keeps the extractor retracted - goes (suddenly) "over-center" and snaps the extractor blade sharply to the rear - producing a sharp click, which propels an empty case rearward so as to strike the ejector stud - located in the rear of the receiver trough - with sufficient force to send the case flying several feet in the air and to the rear. The efficiency of the ejection system is startling to newbies.

The extractor remains "thrown", in other words extended, until the block is closed, with or without a cartridge. The extractor will actually hold the block partly open, perhaps 20 degrees or so.

If your rifle does not operate precisely in this way - you have some mechanical issue(s) which may be causing or exacerbating your chambering problem. This gets back to my question on the other post - do you have personal knowledge of this particular rifle having been fired in modern times?
