Hi

I'd love some advice on the best stainless steel shot to use with my barrel polisher. Small items are fine but if I polish anything slightly bigger - even a ring - there are tiny pit marks all over the silver. The marks really are tiny so the silver almost has a bit of glittery finish rather than being nice and smooth.

I've tried removing all the needles from my shot but I'm still having the same problem. There are tiny balls in the shot and I'm wondering if they're doing it? I've read conflicting information online as to whether small or big shot is better and would like some advice before I splash out on some new shot.

Any ideas?
