Talley rings and Tikka T3 lite Stainless

I'm really new to scopes and how they mount on the rifle, so please bear with me.  I've only installed one scope, and that is on a Tikka.  The rifle came with what I assume, is the mount, already attached to the receiver.  It is a flat piece of steel, attached to the receiver by a pair of screws.  There is bevel on the outside edges of the mount, allowing the factory rings that came with the rifle, to clamp onto.   The ring bases have screws that allow the ring to be tightened down under that bevel.   There are also two holes, one for each ring base, drilled into the beveled mount.   The rings have a small pin that drops into that hole.  So in addition to the clamp, the ring is also held in place by that pin to prevent it from sliding forward or back.  The scope has remained rock solid through several hundred 270 WSM rounds and some arduous hunting treks.   So I have no complaints.
