It might work but it would only be single stack and the lips would need extending (and I only have one magazine and that goes with a gun that still works) the front is too narrow for the 410 to be anything other than single stack.
The rim of the 410 is the same as the 303 so the back end isnt really a problem.

If I go completely box shaped they look like they will stack ok, instead of a hammer formed track to hold the rims back I figure it will be easier to weld in separate plates in the back-sides of the magazine to control the rim, there is still a bit of scope to get some more "bend" in the stack by making the front wider. This may require a bit of trimming in the receiver to fit and will be pretty critical to get the mag height into the receiver correct
