that confirms what i thought.
it seems that some days my chrono is all over the place, or will give me an obviously errant reading once in a while. i just toss out the anomalies, and fire an extra round.
i have wanted to run the same load through different chronographs to see what happens. sounds like i dont need to, but rather just accept the chonograph as providing information that means more for its relation to other readings and not as an instrument with absolute data.
