There is nothing unreasonable in the classes of weapons we are currently allowed to own, (in most states).
You are correct. The people actually pushing this thing again know they will probably lose, but any win at all is a win in their book. Think it through, every state that has passed new gun-control legislation is a feather in their cap. Another state closer to to the final solution.
But on the other side there is a strong push back. Win a state lose a state, maybe more. This is becoming a very polarizing issue and it's exactly this kind of thing that can bring about dramatic shifts in the overall scheme of things.
As soon as the line becomes sharply divided it becomes easier to count the votes and know if it's time for a new Constitutional Amendment or time to shut it down and move on to the next item on the agenda.
