My AR in 72x39 is more accurate with the cheap Wolf/Tula steel case ammo than my very similar .223 AR build is with PMC ball ammo. My hunting loads in my 762x39 bolt action (Howa mini) run just over 1moa consistently, using a .308 bullet in a .310 bore - I should be able to get a sub-moa load going if I ever spend the extra money on .310 bullets....
Steel cases still have the case mouth expanding while firing, etc. just they spring back closer to original spec than brass does. The biggest issue is increased wear on extractors.
None of the cheap steel case stuff has been made with corrosive powder or primers since the old stashes of Norinco, etc. dried up forever ago.
