Right off, it sounds like you have some out of round, which will make the rings rotate, and for the rings to round off, to much ring to piston clearance with let them roll on the edges.
I always use moly + rings. They have the rough abrasive on them. They seat very fast. 150 miles or so. Regular engine oil on the piston and ring assemblies when installing.
I STOPPED USING ENGINE OIL ABOUT 5 YEARS AGO ON THE CYLINDER BORES ,I ALSO SPRAY WD 40,CRC OR SOMETHING LIKE THIS ON THE RINGS AND SPIN THEM ON THE PISTONS.BECAUSE THE ENGINE OIL OF TODAY AS MANY MORE LUBRICANTS IN THAN IT DID 5-10 YEARS AGO AND IF BY CHANCE HE GRABS SYNTHETIC OIL INSTEAD OF CONVENTINAL OIL IT WILL TAKE THAT MUCH LONGER FOR THE RINGS TO SEAT.I DO NOT KNOW OF THE MOLY + RINGS. THE RINGS I USE ARE COATED TO REDUCE (DRAG) AND ARE EXTREMLY HARD AND VERY SMOOTH AND REQIRE A VERY SMOOTH CYLINDER BORE SO THE RING COATING DOES NOT CHIP OFF.
