Date: 2024-03-07

6.5 Creedmoor Load Development and Accurizing my Ruger Precision Rifle. In part 2 of this series, we'll take a look at how the various bullet seating depths affected group sizes. We'll also look at how temperature and Density Altitude affected the velocity of our load from the charge weight testing and, how that affected ES, Group Size and Velocity. We'll also be able to extrapolate how much change in FPS we should see for each degree of change in ambient temperature.
