For your second match you're doing fine. It takes a while to get comfortable running around with a rifle as opposed to a pistol, and movement really is the secret sauce.
My number one suggestion would be to practice coming into your positions with the gun up ready to shoot, and break the shot the second you have a good sight picture. Do this left to right AND right to left.
Also, get to know how fast you can double tap targets based on distance. Some of your splits on close targets were really slow. You don't always need a great sight picture for the second shot....if it's under 10 yards or so, blaze away!
