Re: Target for zeroing with open sights

With regard to wandering POI, I have found that a round bead is often the problem since the apparent center of the bead will shift with light. You will favor the side with more light, not realizing that the portion of the bead in shadow is even there. Filing the bead so that there is a flat facet facing your eye, with a bevel running from closest to the breach at the low point of the bead closest to the muzzles at the high side of the bead will give you greatest contrast for the bead and works great for hunting.

You are quite right about beads and wandering POI.
I wasn't referring to that issue as I do not use beads, for exactly the reason you mention.
What I am referring to is that a rifle zeroed on the bench, particularly a two-piece stocked rifle using traditional benchrest hold {but I've seen it with Mausers, etc, too}, can sometimes shoot differently from a field position. This can be mitigated somewhat by using a two-handed hold on the bench with support hand preventing contact with the front bag, but even so it is good SOP to check zero from sitting, standing, etc to make sure the gun shoots where it will be held in the field.
