Default ballistic coefficient?

Ok so I bought this app, isnipe, but can't find the ammo or even the caliber. This app will give you the performance of a bullet but I need the ballistic coefficient. I have been trying to figure it out but can't find any help on the net so I figured someone in here has to know how or where to find what I'm looking for. I'm using Hornady superformance .22-250 50g. All the reviews for the app was excellent so I figured I'd try it out. Couldn't find my round anywhere. If anyone can help please let me know what I can do.

I believe that hornady has published ballistics charts that provide that information on the bullet. I tried to find a link for you, but apparently my computer no longer likes Hornady's site. It's a Dell.

The true measure is derived by experimentation or reference to a table. Here is a link to an article on estimating the BC of various rounds by their shape.

It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)

"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington
