One of the things I adore about my Mosin is that if the bolt is sticky, or the bullet doesn't want to feed, not only can I slap it around like a red-headed stepchild without fear of breaking it, but manhandling it is actually the proper course of action. It's a hundred year-old design built to be used by illiterate famers in the harsh Siberian winter. When the bolt would freeze to the receiver, a soldier would grab the heaviest thing he could find -- a chunk of wood, a hammer, his booted foot -- and wail on that bolt handle until it released.
Apparently I'm not the only Mosin owner to experience "sticky bolt" syndrome, because over at 7.62x54r.net, they have a humor section entitled "AK vs. AR vs. Mosin-Nagant" filled with typical military dark/gallows humor with the following example:
You know you have an AK if...
You consider it a badge of honor when you get your handguards to burst into flames.
You know you have an AR if...
You consider it a badge of honor when you shoot a sub-MOA 5 shot group.
You know you have a Mosin if...
You consider it a badge of honor when you cycle 5 rounds without the aid of a 2x4.
