Ballistic coefficient

[corbin9191]

When I am using the http://www.eskimo.com/~jbm/calculations/traj/traj.html
Program I go to enter the BC of the bullet that they dont have on the list above. Which "G" factor do I use for the boat tail design? Because they have G1-G8 then it goes to GI and GL. Thank you.

G1 is all I use and so far has proven to be very close calculations to actual range/click testing.

Ok, Thank you. I wasnt sure which drag feature to use so I thought I would ask.

I use G1 here as well.
