In addition, some manufacturers have a tendency to claim higher ballisctic coefficients than their projectiles seem to have, when you test them (many are "calculated" based on shape,rather than determined empirically on an instrumented test range.....)
Yes, which is why one shouldn'trely on published B.C. either for determining trajectory or energy at range. I'm notsaying that the BC with charge is .10, only that this B.C. approximates the trajectory curve Redclub experienced in the field. Thanks to Redclub for sharing data he has a considerable investment in gathering.
I wish I had two chronys.This interests me considerably.
