To be even remotely portable a steam-powered auto-reloading crossbow class weapon would have to contain unimaginable pressure. Easier to make it magic based, or just not have it at all. Bows are better weapons anyway, they just require skill to use where a crossbow was a cheap weapon that untrained soldiers could use en masse.
