Hey ingo,
I just started load work ups with my new chronograph and rl23 for my 280ai.
I shot 8, 3 shot groups with loads from lowest to highest working in small inciments...(.5 -.7 grain increments).
The loads with the lowest es was not the most accurate...varying only 9 and 11 fps.
The most accurate load actually had the highest es of 79fps....i noticed the same thing with h4831sc...to a much higher degree.
Maybe it is my shooting or maybe my chronograph is faulty (caldwell).
Some loads showed lower fps than the previous increment.
I waited 8 to 10 minutes between most strings...go back inside, resize and load the next increment, ...barrel was never hot to the touch, but warm.
Anyone else ever see this? Is there some science behind this?
I would think that the most consistent fps would be the most accurate.
Please and thank you
