I just read the thread "Between Shots During A Round - Your Routine?" and had a similar question but did not want to hijack that thread.
At what point do you close your gun and shoulder it? Too early seems like bad manners, as I have been annoyed by shooters doing stuff to my right before I shoot. Good case for blinders I guess.
On the other hand if you wait too long it draws the match out.
Is there any consensus on the subject? (Fat chance...)
