This time I tried to save linotype
I bought a few range lead ingots, which gave a hardness of 8 bhn. I've been wanting to do this test for a long time.
A friend has a company that paints large metal structures, such as pipes, etc.
So he has a large assortment of electrostatic paints.
He gave me a couple of sample bags, which he considers to be tougher and easily form a thick layer.
So I made a batch of boolits with the MP 135 RNFP mould, I did 4 coats of paint, trying to make them pretty thick.
Then I passed them through the 356 sizing and loaded them, and the first shots showed keyholing, no lead accumulation in the barrel.
The next experiment will be with the addition of very little linotype, bringing the hardness to 10 bhn.
