Using the same target try shooting with the sun to your left.

If you can shoot well enough you will find that with the sun to your right the center of your group will be to the left, and with the sun to your left the center of your group will be to the right.

File the bead to about a 30* angle off vertical and then polish the bead, making sure you keep the facet at a right angle to the bore(s). Using the same target repeat, shooting with the sun to your right and then with the sun to your left. You will find both of your new groups together, in the center of your two previous groups.

What you will have discovered is that your eye focuses on the brightest part of the bead, which when it is round is on the side the sun is on, and when it is flat is the entire bead regardless of the position of the sun. The bead will also appear larger and brighter after it is filed and polished.

I have done this, this is first hand information. Try it and learn if you won't take it as fact from me and others.

Shootaway, it's all about "Averages" . If I shoot several groupes at a time of day when the sun is on my side with tight groups on the opposite, then with the same rifle and numerous tight groups dead on with the sun up above certainly gives us a good average.
Shooting open sights is not too difficult with some practice and reasonable eye sight.

That's right, and that's why so many front sight heights are offered for all of those front sights with changeable beads, and why all of those rear blades or aperatures are adjustable for windage, why scopes have adjustment dials for windage and elevation, and why rim fire scopes have parallax set at 50yds rather than 100, why high magnification target scopes have adjustable parallax, because the sight picture never lies...

Do you not aim for the X even when shooting at 100yds, checking the zero of a scoped rifle you know shoots 2" high at 100yds?

Back to the bead. Try filing it, you will learn, and yes, I already did the shooting to verify that the point of impact does actually change with a round bead and the sun at different aspects.

Shootaway is either the ultimate "puppet master" or an "idiot"......either way I wouldn't waste your time trying to explain simple concepts to him. The experience is always the same......kind of like stepping on a wad of gum on hot pavement.

That's exactly what we have found for years and likewise, shooting at my range at around 9am will always make the group hit to the right.

Another example of a target from last weekend at 50m off hand with bead covering the target. Sights have been set for the six o'clock hold in which the target would have been hit centre had the bead been at the 6 o'clock position on the target. (An "easy fix" with a file).

Yes, from the direction my range faces for a few hours every morning before the sun gets behind the trees it hits my bench. When shooting at that time with a round bead there is a glare on the sun side of the bead. While working with my "new to me" Franz Jaeger drilling this past Saturday at that time of the morning, there was the glare just as it always is on bead sights at that time of day.

I don't care what you say. It is certain that occasionally you must stumble upon the truth. However, you quickly pick yourself up and hurry on as if nothing remarkable happened.

I think if you are telling me that you and your rifle,especially offhand, can shoot absolutely straight at any yardage,repeatedly,your full of BS.Also if one posts target after target of offhand groups at 50yds that IMO could not be possibly shot rested or off the bench then I call BS to that and all things thereafter.
