Get is as good a position as possible and include;
Bone support (as much as possible, the sticks are artificial bones..)
Muscular relaxation (really important not to fight the recoil of a dangerous game gun)
Natural point of aim
Then
Focus on the front sight, intensely!
Align in the rear sight up and down, left and right. (a red dot or scope makes these two steps much easier)
Properly aim the sight, dot, or crosshairs at the target.
Squeeze the trigger without disturbing the sight alignment and aiming point (sight picture)
Provide consistent follow through during recoil (consistent opposition to recoil)
In a Junior Shooting Program that I ran and coached at Quantico during 1984 to 1988, Gary Anderson, 2-time Olympic 300 Meter Gold Medalist would bring his kids. Gary would just sit back and do paperwork while I coached all the kids. I did get to converse with him quite a bit while the kids were changing targets and cleaning up the range. The most important thing I remember was his confirmation that in shooting one has to MASTER the fundamentals of marksmanship. The most basic (other than safety) of which I listed above.
Or one could to refer to Mark Sullivan's video of "Handling a Double Rifle". His catch line is:
"When in a fight, front sight"
