No need to pull any bullets.
When you scrape or 'skin' a plated bullet a section of the plating will wad up and will be stuck to the bullet at the rim. Just take a look, if it's happening, you'll see it.
The first time it happened to me I didn't catch it and it made it's way into my .38 Super 1911 making it jam out of battery.
I don't worry about finding fine brass hairs, I see them more with jacketed bullets and they don't seem to hurt anything.
