After decades of loading without wearing any kind of protection on my hands from handling powder and lead bullets and cleaning and resizing cases and whatnot, a few years ago I started wearing nitrile gloves when handling any cleaning or loading operations. I got to thinking about the lead exposure specifically, not just from the bullets themselves but also from the primer residue on the cases. /QUOTE]
For decades this topic has been debated or at least since Al Gore invented the Internet
Here is thread sticky on it; There are also links within this thread

Bottom line is you DO NOT absorb lead through you skin (like touching bullets) You absorb it through ingestion, your eyes and lungs. Indoor ranges that allow lead ammo are the big sources,and it is mainly from the lead in primers,
You can rub your hands in lead or primers and it is not going into you skin unless you put your finer in you nose or mouth.
Sweeping the floor of an indoor range kicks of lead dust which you then breath or get all over you, so wash you hands , hair and clothes
Now cleaning solvents are a different mater, Some solvents are directly and rapidly absorbed into the skin, eyes and mouth.
I worked in an industry with very toxic chemicals and solvents and was responsible for the all the MSDS and Worker Safety.
Wear gloves if you wish, more so if using harsh solvents for cleaning. That said there are many household products in use under most kitchen sinks or in the garage that are just as bad or worse.
