ligonierbill,
I think the different model numbers are just different barrel configurations( Combo, double rifle, double shotgun, etc, maybe also finish), the ZH actions are all basically alike. A German friend hunted with one in 7x57R/12ga., it was "hell for stout" and strong enough that the rifle barrel is on top.
