6 o'clock hold

[riflejunkie]

Not wanting to infringe on any ownership of artwork or whatever, I'll just post this link to give you an idea of the 6 o'clock hold.  Whether you are shooting with a notched rear sight or a rear peep sight like on the us military rifles and carbines the idea is to place the bullseye on top of your front sight.  It is easier to visually find the exact bottom of the target than the exact center.  Some people like to have a "line of white" between the top of the font post and the bull and some just prefer it touching.  If you are shooting a bullseye that is 3 inches in diameter you simply adjust your sights so that your point of impact is an inch and a half high.

If any of our talented members can do the artwork that wont infringe anything we can do something for our "liberry".

Here's what I teach....
Most important point is sharp focus on the *front* sight only.  
Everything else (bullseye, aperture, rear sight) will be fuzzy.

There is a variation called a SUB-6 hold for pistol shooters.
The difference is the front sight is below the bull with a separation (white) the same as the white on both sides of the front sight.
The idea is you have 3 equal size white on both sides and top of the front sight.

If you are like me, used to a 6-oclock hold, transitioning to a sub-6 is HARD, but I changed to it for AP.  
The brain has to be retrained from MANY years of using a 6-oclock sight picture.
