I couldnt see where it set the bullet deeper in the case. It probably doesnt. We're talking dead soft lead here. Them 22's have a pretty good 'skirt' of lead around them, pull a few and see for yourself. I do a little swaging myself and soft lead flows really easily. You probably just have to barely tap it.
Even assuming it is safe I wouldnt buy one unless they came out with a reloading press version so it could be adjusted and locked down for repeatable consistent results.
This dont look any scarier than Lee's pound your ammo together setup.
