[QUOTE="dsculley, post: 1235364, member: 77514"] When using a chronograph you have to remember that at best they provide a good estimate of MV. No matter what my chronograph says, I always trust my target. If I am shooting what to me are acceptable groups then it really doesn't matter what the chronograph says. I do use a chrony for working up loads, primarily to help watch for over pressure loads. After I identify my load, then I can use my target to determine the standard deviation for the load, but that SD tells me what I can expect my group size to be at other ranges not the SD of the MV. Since it is target engagement that really matters, I feel this is a good method. I am not concerned with the ES of a particular string of shots because that has no real bearing on the expectation of ES in future strings. FWIW, [/QUOTE]
