I shoot Bullseye competition DA with an iron-sighted revolver (except for slow fire). It's great training for how to keep a gun steady. The below target was at 25 yards, one handed DA, rapid fire (5 rounds in 10 seconds, x 2).
Caveats - the trigger pull weight on this gun has been intentionally lightened (but is still a long pull). It's a 6-inch barrel revolver, which helps with recoil and because it has a relatively long sight radius. Also, it's a .22LR - centerfire calibers are going to be a little tougher.
