Ok I have probably missed this somewhere on the site, but, I need a little help for target practice. Know that the CCW course usually is 1, 3, 5, & 7 yards. That is no problem. Also remember that we used some barriers when we did training on the firing range in military. Just can't remember what distances. Been awhile and getting old. I'm shooting S&W 9mm and 22 revolver. I know that I could pick any distance but would like some input from the experts. Thanks for info in advance.
