When you shoot the upper barrel of an over-under shotgun for your first shot, there is a possibility of having to recover from a recoil-induced barrel rise before shooting your second shot.
If you shoot the bottom barrel first, there is a possibility of having straight-line recoil, which makes it possible to shoot the second shot without any barrel rise.
If you’re currently shooting your top barrel first, try changing to your bottom barrel first; you should like it.
