Like the Singlestack said using smaller targets helps. It's one thing to use outline targets for short range rapid fire self defense drills. But when just going for accuracy and trigger/muscle/breath control.... I actually just save myself a lot of money and staple up plain white notecards. I will put up 6 at a time, spaced out, and do slow fire 5 round strings.... I do not lower my weapon between shots... I do not take a lot of time between shots... I just get my sight picture, slowly squeeze.... recover... get my sight picture... slowly squeeze.
You will be amazed at your groups on the small notecards only after a short practice period, and transitioning to rapid fire on a large man sized target, makes you feel like your shooting at the side of a barn and can't miss.
