i shoot mostly Oregon Trail Laser Cast and lubed bullets. have found my time more valuable than casting bullets as i used to do.
however, when i come across some free wheelweights, i cast them into ingots and store them in the barn. never can tell when lead bullets will become non-PC. a ton of lead, and i have more than that, will make around 58,000 240 grain bullets or 88,000 158 grain bullets, as an example.
i fully expect these ingots to ingest some moisture somehow, so will be cautious and always start with a cold pot to liquify them and stay away until that has occurred. molten lead eruption makes a horror story if one is closeby.
yep, i am hoarding, but, you never can tell. EPA is on the march.
