Our flat based bullets only have a G1 coefficient while our boat tails will have both G1 and G7 coefficients. G1 and G7 are two different methods of calculating Ballistics.
G1 is the old system for measuring BC and is suitable for flat based bullets, but many bullet manufacturers use this coefficient for boat tail bullets as well, so we include the G1 information so that you can directly compare our bullets to their bullets.
G7 is an updated equation and the better system of measuring a ballistic coefficient. It provides more accurate and reliable results when calculating trajectory using a ballistics program that allows for a G7 to be used.
