Setup:
Some time ago I bought some 264WM "once fired" brass on GB and they were absolutely spotless. Too spotless. Every time I buy rifle brass used, I anneal it. In spite of the anneal, I lost more than 75% of the cases to neck splits when I sized them, lubed inside and out.
I got back to the seller and he said they were ultrasonic cleaned, and good brass. He contended that the problem was my process. I trust my process.
Question:
Does ultrasonic cleaning work harden brass? Even if it did my annealing should have alleviated at least some of that.
