"downrange training" is a particular peeve of mine.
If things go right, you end up with a bullet in the back stop to no real purpose, if things go wrong, someones brains land there.
No sane, responsible, trainer would engage in such stupidity.
I have to side with MB on the "no bad training", with the caveat that the student has to already have some basic knowledge, in that case any time behind the trigger allows you to practice basics of sight alignment and trigger control.
For the absolute beginner, there
is "Bad training" out there and it can get beginners killed.
Beware of any school or Instructor that "guarantees" to make you an "expert .
Remember the Fred Vallari "Karate schools" that guaranteed you'd be a Black belt in 6 months ?

That's bad training, it got peoples butts beaten in fights and in shooting it can get people killed.
