Also, manipulation drills should not be done with guns and live ammo, at public ranges (or private ranges with others in vicinity).
This is why they make snap caps, and workshops, basements, garages, or possibly living rooms. (Living rooms are iffy, depending on presence and attitudes of family members.)
This is also why it's nice to have access to remote, outdoor ranges, in case one wants to try to train with live ammo in a more forgiving environment. That's more advanced, though. Snap caps are the way to go, initially.
