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.
