The BIG thing to remember with a right to left and presuming you are right handed, is FOOT POSITION. Your feet need to be pointing towards the point where you intend to kill the target. Any further left and you would run out of swing and drop your right shoulder. So on the skeet layout from peg 4 position, your feet should be pointing just to right of the centre of the layout. Start at peg 2 and shoot all left to right targets, then move to 3 and so on. If you are struggling, go back 1 peg or halfway between the 2 pegs, only moving on when you can fix the sight picture in your head. Do not be tempted to look at the trap house, come out by about 3 metres as your look for target point.
