Even if you NEVER shoot it - it looks GREAT over a fireplace mantle.
Really though, it’s much more fun to shoot.
Also, if the bolt DOES bind up on ejection, pull back on the safety screw to cock the bolt. That way when you work the handle, all the force is working to twist the bolt open, and none of it is going towards cocking the bolt.
Then follow with a short drill/brush session as described earlier.
Final word of caution: Mosins have a tendency to multiply over time.
