Frankly, with lead bullets (I load mostly Missouri Bullets) I tend to think that shaving a bit of lead is better than belling the case too much.
If you take a look at your size case, when loaded with a lead projectile, you can visually see the bulge in the case where the bullet occupies the brass. This helps create neck tension I would assume (I defer to SS as always, talk about knowledge comparison... like comparing a ford pinto to a Ferrari...) so honestly if you shave 0.003'' off your projectile but still have a good neck tension and crimp, I don't believe you are going to see any noticeable difference in your ammunition's performance on the range. Better to dial your press in so this doesn't happen, but as crbutler suggests, I think some of this is caused by the bullet not being perfectly vertical as it's seated into the case by the press.
All things being relative, we are loading cheap pistol ammo when we load lead (at least I am), no matter how I set my Dillon 550 to bell the case, without fail I will find a round here and there (maybe 1-2%) that have lead shaved off. No big deal, take your finger, remove the lead shaving, life goes on. This, assuming you've not got any of the trouble that SS mentions. But, keep in mind, I say this based on the scenario of what I do. I load bare lead to the light side of any manual recommended charge. So any trouble discussed in this thread that might occur is somewhat mitigated by that.
Besides, if I wanted to push the envelope, bare lead is not what I'd choose to do it with.
