Sight Radius & Sight Settings - TexasMac - 08-26-2013
Guys,
I just posted a short article on my website titled “Sight Radius & Sight Settings”. If you’re interested in reading it go to http://www.texas-mac.com/Sight_Radius_and_Sight_Settings.html.

Guys,
I was just made aware of why 36” is the ideal sight radius for a BPCR with a soule tang sight. Since many BPCR shooters these days speak in terms of points rather than MOA, implying sight changes in increments of 0.010" and assume that one point makes a change of 1" at 100 yds. Therefore the ideal sight radius is 36" rather than approximately 34" and the article needs to be modified accordingly.
Regards,
Wayne

Front sight height plays a huge role in how many point/minutes/marks the soule or vernier has to use to get to any given yardage. You can take the same rifle , put 3 different sight heights on it, use the same load and get 3 different base comeups for any given yardage.

The article has been rewritten. Hopefully it now does a better job of reflecting conventional wisdom.

I just updated the article and changed the title to Sight Setting - MOAs vs. Points. Hopefully it now does a better job of explaining the differences. If interested, go to:

Informative read Wayne, thanks.
As I have a 33.25" sight radius on my roller, my marks/lines of sight-adjustment for a distance are just that, lines or marks. Whatever it takes, is what it takes.
Old guys got simple ways,
Jim
