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 standard table, so just leave the G1 setting. However,
if you are a professional or one of the growing number of
shooters that want to experiment and learn more about exterior
ballistics, then you will be interested in this information.
The drag tables supplied with Ballistic
Explorer include the following:
| Table |
Description |
| G1 |
Standard table for all
sporting bullets |
| G5 |
Table for low base drag
bullets (BT) |
| G6 |
Table for flat base &
sharp nose bullets |
| G7 |
Table for Very Low Drag
(VLD) bullets |
| GL |
Table for exposed lead
nose & HP bullets |
| GS |
Table for spherical bullets |
| RA-4 |
Table for rimfire bullets |
Ballistic Explore supports up to 20 drag tables.
Each trace window can be set to a different drag table, so
it's easy to compare the results, and version 5.5.x now lets
you convert the BC of one table to the equivalent BC of another
table at the current muzzle velocity. These tables are just
text files with a file extension of DCT. The program's on-line
help gives the complete specifications for the file format.
Advanced users can (and do) create their own drag tables for
such things as paintballs and airgun pellets.
All of the provided tables are derived from
the equivalent SAAMI
table and are used with permission.
