Looking at my 450 magazines and comparing them to the 410 mag picture..It looks like the 410 feed lips are much shorter than my metal 450 BM mags.

The first couple minutes of this video show the magazine. Looks to be two sets of feed lips, front and back. I don't know if the front set would capture the front of the .450 Bushmaster case. Your guess is as good as mine, until someone gets one in their hand and tries it.

In the video, it looks like the front lips are lower and wider spaced than the rear ones. Probably function just to keep the .410 rounds centered as they rise up at the ready to be stripped by the bolt. My guess would be that as the bolt picks up a 450b round and it begins moving forward, it will pop free too soon and possibly malign before its close enough to the feed ramp in the upper to be properly guided into the chamber. Maybe not but that's how it looks to my mind's eye.
