Nope...I practice with birdshot. Shotguns are point and shoot. I'm not saying there isn't aiming involved, I'm saying pinpoint accuracy it not a big deal with one (get a shot in a torso and you're doing fine...and that's a pretty big target at 8-12'), especially at the short distances found in the home.
With that said...I believe muscle memory concerning the pump action are essential...as it weapon handling. I run cheap-o $22/100rds target loads through mine. I do run 00 buck from time to time in the form of $4/5rds Win military surplus but not the more expensive Hornady TAP I keep loaded in it...it would cost a fortune.
