I understand and agree with statistical deviations in group size with any given load, but I have seen some threads interpreting Bryan’s analysis as meaning load development is futile and they’ll all shoot the same with a big enough sample size. My own experience has shown me that that is not true. You CAN develop a load that averages better than another, but there will always be a range of group sizes with any given load.

John,

Agreed. Bryan mentioned a typical SD of 30% of the mean group size. The absolute mean and SD will vary with different loads and rifles. His point was definitely not that load development doesn’t matter.
