Here is a couple of cut away drawings showing what the insides of a Winchester 94 looks like in both open and closed positions.
The forward end of most of the Win 94 cartridge carriers are notched to sit low in the receiver around the cartridge stop. This notch varies from deep as in the pre-64 carrier shown in the picture above, to shallow in some of the post-64 carriers. The .357 carriers found in the later USRAC guns are much shorter than the other carriers and have no notch.
Study the pic and you can easily see what happens to cause an under the carrier jam. When the cartridge stop breaks off, wears down or tolerances stack up wrong, the cartridge will slip over it and end up between the open link and raised carrier. At this point clearing the jam usually requires at least partial disassembly of the rifle.
The problem can be cured in a number of ways:
A: Replace the link
B: Cold swage the cartridge stop to a longer length and then reshape it with a file. This only works if the problem is minor wear or a tolerance problem.
C: Weld up the stop and reshape it.
I hope this helps explain the "Under The Carrier Jam" Winchester 94s are occasionally beset with.
There is one other fix I've had some success using with the 357's. Part of the problem with the late 94's is Win tried to make the parts, one-size-fits-all. In other words they left things kind of loose to eliminate as much hand fitting as possible. There where the link is pinned into the receiver is a good example. When someone sent a 357 that was feeding under the carrier I would order a new link and the install it using a custom made oversize link pin. Then drill both the receiver and the link for a tight pin fit. By removing the slack there at the pin this made the cart stop come back to the same place each time.
