On my own not so much. Trips to the range on my own time are more leisurely pursuits. Most of the military shooting I have done in the last ten years or so have been stress shoots (except qualifications).
I would say that stress shoots are absolutely essential for anyone who takes self defense seriously. You will never be able to recreate the anxiety levels of a life and death situations properly but you can emulate them by physically taxing yourself.
Instead, just follow the advice of Wild Bill Hickock.
Shoot slow and precise, very very fast, and be the first one to do it.
That is not great advice. Wild Bill was nearly blind and killed one of his good friends accidentally doing just what he said.
