Nalioth - All Saigas might have the "case neck step/ring", but mine does not. I have five Fiocchi brass cases with no mark on the neck of any of them. The Saiga is a Sporter model, certificate 26 February 2009. I looked carefully at the photos in the Sticky for neck expansion for Saigas, but do not have that at all. No big deal, just that this one does not have that "feature". I just lucked out with dimples, a PG hole and no "civilian chamber magic".
You definitely lucked out getting all 3 features, (barrel w/ mil-spec chamber, magwell dimples, factory pg hole), on a standard "sporter" Saiga rifle.
Perhaps you should go pick up a couple lotto tickets.
