Flitz and Nu Polish with Walnut. Corncob if I wanta show off.
Gave up on SS Pins couple years ago - they messed with my sd's. If I was using range brass or really old brass I would use the SS Pins.
If you use the ss Pins in a wet tumbler get some Blaster Graphite Spray Lube, Spray 3/8 inch in the cap or a small cup - ( tilt cup on an angle) dip neck in graphite, wipe outside, set neck down in your tray. This helps your bullet release more consistently since you got rid of all the carbon tumbling.
