Does anyone know how much room is left in the Henry rimfire lever action? They would seem to be easy to mass produce and the action is pretty smooth. I've wanted a small caliber to cast and reload and was just curious if such a thing could be made. I doubt it would ever really be popular enough for mass production but I wonder if the action is even strong enough. I know they have made the Henry in .22 WMR but I think the Hornet is a little higher in pressure.
