Drag tables are also know as drag functions
or drag models. Don't be concerned if you don't know much
about drag tables. The only thing you need to know is that
G1 is the default table, so just leave G1 selected. However,
if you're a professional or one of the growing number of shooters
who want to experiment and learn more about exterior ballistics,
then you will be interested in this information.
Standard drag tables apply to groups of bullets
with similar characteristics while Custom drag tables are
specific to a particular bullet. The Standard drag tables
supplied with Ballistic Explorer
include the following:
| Table |

The G2, G8, and GI Standard tables are derived
from public sources, while all the rest in the table above
are derived from the equivalent SAAMI
table and are used with permission.
In addition, over 50 Custom drag tables are
included with Ballistic Explore. Most of these Custom drag
tables are published by Lapua and are included with their
permission. The Lapua drag tables include "Lapua"
in the description when viewed in the Select
Drag Table dialog.
