Mr thornette, Just throwing it out there, but my eyes are older than my two tapered post reticle scopes and I have gone to using electrical tape to make a "vee" about 6 inches tall with about 30-35 deg arms with a horizontal flat bottom on buff or light brown cardboard. The sight picture with a small band of white between the top of the tapered post and the bottom of the vee provide a very precise and repeatable sight picture. It ain't my idea, though, the US military used a vee target for a half a century at least.
