Agreed. I avoid swaged lead bullets myself. It's not always about leading issues, but I've yet to see a soft swaged lead bullet that's as accurate as a good WW alloy cast bullet in anything except the very lowest pressure plinking loads. Even in those very mild loads, I get better accuracy from 10-12 BHN than I do from 5-6 BHN as swaged bullets usually are.

Also those "jacketed" bullets are not jacketed, they're just a thin copper plating over the soft swaged lead.
