Anything Wrong With using Polymer-Coated Steel Case Ammo in Guns ?

I know we all like to stock up on ammo best we can, also stay in practice with our weapons. As I am always looking for the best deals on ammo, I keep running across these Russian polymer-coated steel case ammo. Of course in my Mosin-Nagant, I buy this without second thought, I figured it was what it was made to use, but in my other guns I am honestly, quite leary. Now this ammo is non-corrosive, but still I have a hang up with steel case ammo even if it is polymer coated.
I am not going to claim I have the best weapons money can buy, but I think I have good quality weapons, and I don't want to do damage to them trying to save a few dollars on ammo. Is this steel case ammo ok to fire in these weapons?, or would a person be causing undue wear on weapons designed to handle brass-cased ammo? Anyone have an opinion, I'd like to read it, thanks. -dave-

My thoughts on the steel cased stuff:

Read your owners manuals or call the manufacturers to see if it's ok in their guns before you use it. One manufacturer (Ruger) in particular says not to use it. Rumors have been floating around the internet for a couple years about the steel cased Berdan primed ammo causing broken firing pins in the Mini-30. The theory behind the rumors seems solid to me so I wouldn't use it if I owned a Mini-30. Otherwise if the manufacturer says it's ok then go ahead and run it but I'd plan on being a little more diligent in my cleanings.
