Usually I store my ammo and bullets in air tight containers, but there was a box that I left out for maybe a year and it has some white oxidation on it now and it's hard to get off
Are these no good anymore?
What's the best way to store lead bullets?

Are these copper jacketed bullets or uncoated lead bullets?

Are these copper jacketed bullets or uncoated lead bullets?

Are they powder or Alox coated? The coating should protect the lead from oxidation but maybe not.

White stuff on lead is not oxidation.
Lead oxide is yellow colored.
That white stuff is probably lead carbonate.
Which means the lead that was used might have some car battery in it.
Where these cast boolits made locally?
Good boolit casters know not to use car battery lead. Too much chemical contamination.
However it's possible that the caster used salvaged fishing weights.
Guys who make fishing weights are not picky about their alloy.

The lead carbonate won't hurt your gun as the steel bbl is much harder than that stuff.
My only concern would be airborne lead carbonate particles.
If there aren't too many I wouldn't worry. ....If it is thousands, I would get paranoid.

Questions.
1.How many you got?
2. Can you show me a picture of the boolits?

That's what I was wondering. I've seen both white and yellow corrosion on bullets but could be from the photography.

Maybe use a liquid lube to try and take the white substance off? What product do you suggest, alox?

I guess pour some liquid alox onto a rag and wipe the heads boolits down without getting it on the brass until it dries.

the bullets in question haven't been reloaded yet, so they're not in the brass yet.
i'll give it a try tonight, although I don't have any alox
i'll just try see if it'll clean off with some ballistol or something for now
