I'm still hanging out to see where this goes.
Tax payer dollars spent to determine the best weight for LEO use has nothing to do with what actually works for an individual shooter. If the 44 Magnum was the subject of a study funded by tax payer dollars to determine the best weight for LEO use I highly doubt they would settle on 300 grains as best. For my purpose 300 grains is a very useful weight for the 44 magnum.
