I started keeping lead-removal wipes in all my range bags after this. The number of times I've seen people go through 500-1k rounds at the range in the morning during a class, then eat a sandwich or something without even washing hands, is..a lot.
.22 ammo is the worst in this regard, just lead everywhere - which given that it's usually used in bulk given how cheap it is...
(I'm pretty much a 9mm shooter (124gr CCI/Speer TMJ Lawman 124gr, or Gold Dots -- or SIG Frangible when I'm at SIG Academy or TR; 5.56 ranging from cheap M193 to M855 to non-penetrator 62gr to 75gr or 77gr TAP or OTM/IMI Razorcore. I also run a fair bit of 12ga. Worst thing I do is a RH X95 bullpup, suppressed, in off-hand drills, which is basically all the exhaust in my face/neck area on every shot.)
Make the plunge and pay for a lead test that you'll trust and then be satisfied with the results if they come back OK.
And remember that vitamin C increases excretion of lead in small furry mammals.
Lead can be the cause of mental retardation and blindness in toddlers and babies also.
My experience with trying to get a medical professional to actually give a shit about the matter is exceptionally frustrating. Every doctor that I've ever spoken to have all come just short of laughing in my face when I try to self diagnose myself, and without exception, try to send me to get blood tests - which give no indication of lead poisoning except in recent exposure. I really just want some closure on this, since I know there's not much I can do treatment wise. Getting a doctor to take it seriously is an uphill battle...
