    Hey all, just got a new Chrony and took it to the range this last weekend with my hunting load (.308 Win 168 TSX over 42.3 H4895 @2.825"). Avarage speed was 2694fps with an extreme spread of 19fps for 5 shots that landed in a .56 moa group at 100yds.

    What does the chrono tell us in regards to handloading other than the ES, Avarage speed, SD, calculated trajectories, etc...? And how can we apply this info to handloading in the future?

    Do bullets that are similar in length and weight usually shoot similarly if pushed at the same speed regardless of powder and burn rates (assuming that there aren't any high-pressure signs left on the brass)?

    Know of any suggested reading?
