A final test would be to use your barrel as a gauge. I have never had a problem with nines that had just the rim above the gauge, but set aside any that have the groove showing. I use these in several PC nines that do have tighter chambers so there should be no problem in production nines. I mark all the oversize ones and find that they usually go through my standard guns without a problem, but then dispose of that brass afterwards. I find loading brass of unknown firings around 5% come out oversized.
