Did you deglaze the cylinder before you installed the new rings?
I used a piece of sandpaper to give it as good a crosshatch as I could manage by hand.
Moot point, because I actually ended up putting another set of rings in, because it turns out the set I had put in there previously were used.
This time, I found a 3-stone hone and gave it a good cross-hatch before installing an NOS set of standard rings.
