Mud Test: The WW1 & WW2 Mosin-Nagant
The Mosin-Nagant M91/30, despite its historical significance in WWI and WWII, demonstrated poor reliability in a mud test due to its exposed locking surfaces. The rifle jammed quickly when mud and pebbles entered the action, requiring extensive field stripping and cleaning to clear. This performance was contrasted unfavorably with designs like the Winchester 1895, which offered better protection against environmental contaminants.
