A closer target is a great idea, (make it close enough and choose an appropriate aiming point to keep your point of aim as precise as possible), but please don't skip the ball and dummy drill because of your confidence. Try it and prove to yourself that you don't have any issues with anticipating recoil, and driving the gun down.
Consider this: In slow fire, if you focus on the pure basics of a steady sight picture as the trigger breaks, your grip means squat. Slavex on here has done the demo of holding the gun upside down and has used the pinky on his weak hand to pull the trigger. He can shoot better groups using that method that I suspect many people on this forum can, when using the "proper" technique. The reason is that he knows to hold the gun steady, (much easier with a conventional 2-handed grip), and ease that trigger back without moving the sights.
So you are either screwing up the muzzle direction when the trigger breaks and not noticing the movement, or are doing everything perfectly and need to adjust the sights.
