I was the recipient of a Chrony for Christmas!
I was finally able to take it out for a test drive today. It was pretty neat having it and seeing what my handloads and guns do.
Now what does the info that I obtained mean? How do I use this data?
I tried 2 guns today. 1 glock 10mm and a 1911 10mm.
The Glock with its 4 something inch barrel was getting about 1130 FPS on average. The extreme spread however was anywhere from 40-60 FPS per string.
The 1911 with its 5 inch barrel was getting about 1180 on average but the extreme spread was 30 something on both strings of 10 shots.
So near as I can tell your spread is pretty affected by the gun too and not just how carefully your handloading.
Obviously I need to tinker somemore with this thing to figure it out. But can someone give me a How-to on how to use this Data to improve my Loadings? Or, what will I see from the Data that Im producing quality ammo?
Also what does standard deviation Mean?
