Will an ultrasonic cleaner actually remove lead from rifling?
Like most, I've use Hoppes No. 9 and other solvents, along with a wire brush to clean a barrel.
But even my bright shiny 'cleanest' still had lead in the grooves. The lands were always pretty clean.
Using this:
got the lead out.
Several passes ended up with a clean screen ( the small round wire disc) a brighter bore, and a tighter group.
I'd be surprised if an ultrasonic cleaner worked that miracle.
