My Anschutz sights have the finer 1/10 MOA adjustments on my Schuetzen rifle and their precision adjustments for light with an adjustable rear iris has won me many benchrest competitions.
Lones Wigger also used the Anschutz front and rear sights when he won the 1995 and 1999 International Schuetzenfest Benchrest Championship and that is why I have used them ever since 1996 for my Schuetzen competitions.
Even my Burris scope had 1/8 MOA adjustments and also had an adjustable internal iris to balance light variations which even helped me win scope benchrest competitions as well at early dawn or late dusk light conditions.
It ussually requires at least two clicks of elevation adjustment for a light change to correct for the change in point of aim due to the changed light reflection from the change in light intensity.
The adjustable rear iris changes the balance of light and helps change the focus from the target to the front sight which affects your eye's ability to better concentrate on centering the target in the aperture.
Light changes during the competition are ussaully met with a sight adjustment to compensate for change in POA and do not require a rebalancing of the light coming through either the front or rear aperture.
You adjust the front aperture size at the start of the shoot and balance the light as well as focus your sights with the rear adjustable rear iris.
You rarely adjust with changes to light conditions by adjusting your rear adjustable aperture to maintain the correct light balance unless you start getting glare or there is a major change in light intensity at dawn or dusk.
Unfortunately for some you can lead the horse to water but you cannot make him drink.
Best to listen to the advice of those who have won major shooting comptitions.
MartiniBelgian you are contradicting the advice of Lones Wigger the most recognized shooter and most acclaimed shooter in the World.
Lones Wigger in 2008, was inducted into the U.S. Olympic Hall of Fame as well as the U.S. International Shooting Hall of Fame.
Wigger was selected by the United States Olympic Committee in 1996 as one of the 100 Golden American Olympians — an honor bestowed on the 100th year of the modern Olympics.
