Before swapping sights, check to see just how high the impacts are. I use the 6 O’Clock hold on pistol shooting and found that having the target visible makes a big difference in precise aiming.

So, if the impact is a few inches high at 100 yards, put the rabbit on top of the post. Similarly, put the top of of the post 1/3 of the way up a deer’s chest, etc.

Your personal calibration will of course depend on the game and ranges you plan to hunt.
