    Kestrel's explanation -

    G1 has been around for ever and the G7 is as ebf points out better suited for modern projectiles.
    Most (all?) ballistic calculators now let you enter either.
    One thing though, if using G7 remember to tell your calculator that you are using G7 otherwise you get seemingly poor results.

    The Norma figures you have posted are quiet high/good, if actually totally true. There was a time when manufacturers were telling porkies re their projectile BC's.
