P.S.
After Sunday's match, I know I need better sights SOON. Light was poor and a Hadley or other adjustable aperture eyepiece was needed, and I was not getting POI changes to match the adjustments I was making.
I will most likely buy a set of Baldwin Midrange rear and globe front with spirit level. It may take me a while to get used to the left hand threads - like Highpower sights - but the quality is unbeatable.
The old Shaver Conversion and Lyman will be for sale when I get their replacements. OK for Cowboy "long range" or beginning BPCR but as my coach said "You are shooting well enough now that better sights will help your scores."
