Watch your hold carefully and be sure to know where the line of sight is at discharge. It is only in this way that the habit of calling shots, which is essential to good shooting, can be acquired.
Study the conditions, adjust the sling, and set the sight before going to the firing point.
Look at the sight adjustment before each shot and see that it has not changed.
If sure of your hold and if the hit is not as called, determine and make FULL correction in elevation and windage to put the next shot in the bull's-eye.
Keep a written record of the weather conditions and the corresponding elevation and windage for each day's firing.
Less elevation will generally be required on hot days; on wet days; in a bright sunlight; with a 6 o'clock wind; or with a cold barrel.
More elevation will generally be required on cold days; on very dry days; with a 12 o'clock wind; with a hot barrel; in a dull or cloudy light.
The upper band should not be tight enough to bind the barrel.
Do not put a cartridge into the chamber until ready to fire. Do not place cartridges in the sun. They will get hot and shoot high.
Do not rub the eyes—especially the sighting eye.
