Bottom target, then top. When there are two (2) targets set up, one on top of the other, you should always shoot the bottom target first, then the top target. There are two (2) reasons for this:
(1) If you are a standard shooter, your second shot on the bottom target will naturally rise to the top target in recoil - you don't have to add any effort to your gun.
(2) If you can't see it, you can't shoot it. If you shoot the top target first, you can't see the bottom target out of your peripheral vision. You have to move your gun down until you see the target; then aquire the sight picture. If you are going up, you already see the next target to shoot - all you have to do is aquire the sight picture.
