Drag Tables
Drag Tables are nothing more than a list of the atmospheric retardation, in feet per second, on a particular size, shape and weight bullet at various velocitys throughout a useful trajectory range. The G1 Table was constructed using a projectile such as the one described by Gen. Julian S. Hatcher in Hatcher's Notebook.
These tables are generally constructed in 10 fps increments starting at zero fps and extending as high as 4,000 fps
G1....The drag table used by most manufactures and ballistic programs, whether it best represents the projectile or not.
GL....For Spire pointed, soft lead tipped projectiles where the soft lead nose deforms at higher velocities, it is identical to the G1 table at velocitys below 1300 fps.
G6....Full metal jacketed, spire pointed, flat based bullets comform well to this one.
G5....This one conforms to the boattail, spire pointed, jacketed bullets.J1......For very long nosed and long boattail bullets.
RB....The British Roundball test firings were used for this one.
