Steel ammo is most often Berdan primed, some say the Berdan primers are hard on the firing pin and some say a special (longer) pin is needed for reliable ignition. YMMV

I am shooting wolf military steel case coated berdan primed ammo and its great shooting stuff. I guess some guns can be picky and you need to buy a box or two of the steel case to try it prior to buying a case to make sure. It may end up gumming up your action after a while, but I dont know because I scrub mine after each session...
