The ranges in my area - have strict rules on no steel or aluminum cases in ammo.../ and I reload, so I stick with brass ( and I respect the rules of the ranges I frequent).
I don't know that steel cases cause any issues in any gun ...in the few cases where I've looked at guns that have fired a few boxes of steel it was significantly dirtier - but that can be for all kinds of reasons.
I wouldn't mix them with brass either...
