Oleg,
Next time you get the opportunity to fire one try feet, knees, hips, shoulders square to the target; strong foot dropped slightly to the rear; little bit of knee bend, little bit of weight transfer forward; weapon pulled tightly into the body mount with shoulders rolled forward; don't relax this platform until you release the trigger.
I guarantee that you'll keep every round in a single press-off of a full mag, from the 1st to 30th, in a group no larger than your palm from 3M and shorter presses in even tighter groups. I've accomplished, instructed and witnessed equal or better results, static and while firing on the move just by locking into the 'HK stance' (USP/Universal Shooting Platform) that I've described.
