Question: Why don’t we aim or keep the sights directly in the bullseye or the black ring of the 10 m target?
While this may be a great idea while shooting in Bullseye shooting competitions, however in the ISSF format the common practice is to keep the sights somewhere between the bottom edge of the target and the bottom edge of the bull or black circle (7th ring).
Your sights, both rear and the front sight are black in colour. Therefore when you aim directly in the black, the sights gap between the front and rear sights are also black and it becomes very difficult to get a correct sight alignment.
However, if you choose to aim the sights between the bottom edge of the target and the bottom edge of the 7th ring, (black), the sight gap between the front and rear sights is white or bright yellow.
This contrast in background colour makes the sight alignment process much easier. Hence the sights are maintained somewhere between the 3rd, 4th or 5th ring.
