Hmmm...Could they do a 1A instead of a S?
In principal though, a .44 mag should be fairly popular. Be a nice companion to a .44 Mag revo, of which I have a couple. It would also be helpful, if they choose chamber & throat dimensions that work well with quality revolver loads.
The .30-30 in a 1A was done previously, but they are not common, and I bet they'd sell all they make.
