People likely get messed up with the Russian chargers because nobody seems to know how to load them. They work fine if you look at Plate LXII, facing Page 192, of the "Text Book of Small Arms, 1909". The Russian charger is shown in X-ray view (as a drawing, mind you) and clearly shows the rounds loaded in three layers. Outside rounds lie in contact with the charger, inside rounds with their rims riding atop the rims of the outside rounds; the centre round rides on top of the inner rims of the inside rounds. It makes a PYRAMID, with the centre round the apex.
Load them like this and they work fine in Noisy Maggots and Tokawhatevers both. Likely they would work also in Dragowhatzitses as well, but I live in a free country: I can't have one of those.
But, to get serious, they do work in Moisin-Nagants and Tokarevs quite well.
Enjoy.
Make lots of noise.
Have fun.
