I don't see any reason not to. There are some gun gurus on Youtub channel compared the steel and brass casing. The steel is not really harder than brass in the ammo. Hence, not real caused more wear in a long run. I would use steel casing any time on all my Rugers as long as they are factory made meeting the SAAMI standard that Ruger calls for. Especially a time like this, you'll be luck if you could find the right caliber ammo on the shelf Steel or not. Good luck.
