Hey thanks you guys. The measurement of my fornt sight was an approximation because I tried measuring it in place on the barrel, with no straight side to measure from. Mine is probably a .570 too.
It seems that my problem is the large buckhorn in contrast with the narrow front blade and the large bead. My Winchester 94 Trapper has a wider front blade with no bead and the rear sight with much less of a buckhorn (nearly flat) and I never have any problems shooting it. I think my problem lies more in the sight style rather than failing eyesight, although admittedly, they are getting old. Another thing that seems to throw me off is the white triangle on the rear sight. It almost appears like it's not dead center when lining up the sights with a target....keeps me guessing when I'm shooting.
As for the glasses mounted "doo-hicky", while it may work very well at a bench, I just can't imagine walking the field with a big "glob" stuck to my glasses. I'd more than likely trip and fall on my butt and end up shooting myself of someone else.
This may sound crazy but I may try the Lyman globe sight with crosshairs up front and the Marble's bullseye sight in back.
As another option; I have a 30-30 barrel to fit my CR-45 but haven't used it yet. It has some very nice sights on it. I think they're the standard sight from a Handi.
I'd be willing to get another set of those if possible. Can these be purchased from any of the aftermarket suppliers; Midway, MidSouth, etc?
Thanks again guys!
Chris
