When you are in the field shooting from a mountain side using field positions, the drift will make no difference at game ranges.
For a sniper shooting at 1,000 yds or more it would, but not to a hunter.
Go to the range, shoot from a sitting position out to 500 yards and see how you do.
Ecclesiastes 12:13 *¶Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man.
14 *For God shall bring every work into judgment, with every secret thing, whether it be good, or whether it be evil.
