Oxidized booklets?

[Mach_Cat]

I have a couple boxes of 22rf where the lead has oxidized.
Can these still be used without damage to the barrel?
Any way to remove the oxidation?
Thanks ed

I have seen cast and lubed bullets develop a white deposit over years......I think its more likely a reaction between lead and lube,stearate on 22s.........anyhoo,the compound is soft ,rubbing /polishing the bullets will remove whats left of the lube,and you may get leading........so shoot them as they are.....provided theyre clean of dust or grit.......lead sheet on a roof doesnt seem to oxidise noticeably.

I had several boxes of Winchester Super X that became corroded on the knurling on the bullet. These had the copper plated bullet. It prevented easy chambering in my Remington 541T and my CZ 455 American. The corrosion was extremely sharp and gritty feeling to the touch. I figured damage would occur to the throat and bore if I tried to use them. I pitched them all.

I've dry tumbled such things in corn cob and then lightly lubed with JPW.

That was at the worst of the shortage, but I can say they shot fine.

That whiteish looking powder is lead oxide and is very toxic. You can wipe if off but do it outside with a stiff wind at your side.
relube the bullet with something and wash your hands

I think Calamity Jake is right. It probably isn't a great danger, but if I was on an indoor range and I knew someone was shooting a lot of that stuff, I would quietly ask the range officer if they ought to be discouraged, and if he saw no need, I would remember an appointment elsewhere.
