Why the heck is it called a sight radius?
I've been shooting now for almost twenty years and this morning it finally hit me that the term makes absolutely no sense whatsoever.

I'm pretty sure it is a borrowed term from the artillery boys and their first mechanical sight.

Fantastic. You just put my inner Aspie in a round room and told her to sit in the corner. Thanks a lot.
Inquiring minds want to know...
At least you can find a true radius in a round room...Originally Posted by Tamara

Somebody can post what I mean...
Fairness leads to extinction much faster than harsh parameters.
I remember reading something that referred to it as the "sighting line" which made a whole lot more sense to me than radius.
In my mind, we're working on an arc of a circle when tweaking the POI. Naturally, the distance between the sights is a factor when playing with the POI and the sight height(s).

In a sort of ghastly simplicity we remove the organ and demand the function. We make men without chests and expect of them virtue and enterprise. We laugh at honour and are shocked to find traitors in our midst. We castrate and bid the geldings be fruitful.” ― C.S. Lewis, The Abolition of Man
The above is explaining what I understand sight radius to mean. Sight radius is being able to take a measured distance between front and rear sights and to be able to calculate POI shift for a given bullet trajectory when making graduation changes to the sights. This can get you close to POI without actually shooting to make adjustments.

I believe that sight base distance would be more correct when talking about the shooters ability to reduce the deviation of error of aligning sights as the sight base distance increases margin of error decreases.
Dawson Precision has a handy calculation to determine front sight POA / POI adjustments. It worked perfectly for me on the P30.
They use the term in question.
