Magic?

'ShasVre' - Welcome to the KCA Forum. Actually, your question is a very good one.

I don't know for sure, but, I imagine with the 'doubling back', relatively light carrier/follower spring tension, and 'speed bumps', that Olle and Erik designed into the Krag-Jorgensen feed-path, the lead cartridge is momentarily separated, lifted, and moves in front of the cartridge following it.

They did work very hard on the mechanics and ergonomics of their action design. The first two 'Contracts', (Danish model 1889 and U.S. model 1892), were for rifles that utilized rimmed cartridges.

When you look at the drawings, the Krag action looks like a 'recipe' for rim jams.

I have never experienced a rim jam with a Krag, (or a French Berthier, for that matter).

It is very easy to have rim jams with a Lee-Enfield, if you don't carefully over-lap rims in the 'charger' with each cartridge rim in front of the one below it.
Then you have to orient and insert the 'charger' properly into the guides. (There is an 'upside' and a 'downside').
