He does PC the bottom, and I'd say roughly 2/3 of his home cast bullets are fine.
Here are 2 more, the one on the left I'll load, but if you look closely the one on the right has exposed lead. That one I won't load.
The bullet on the right is very similar looking to some of the commercially purchased bullets I got from SNS right after they started offering PC bullets a few years ago. I didn't closely inspect the bullets before loading them, it was only recently that I discovered this. Those bullets are all gone now.
I had gone through de-leading my barrels, and over the weekend I grabbed some older reloads without even thinking about it and now I've got a leaded barrel again.
I'm just going to burn all that old stuff through the gun and then go to battle with the barrel. But that is the last time, I swear!
