9MM Berry 115gr (P) RN and BlueBullet (L) RN ballistic coefficients?

[sbwaters]

Hi, all . . . Anyone have the ballistic coefficients for 9MM Berry 115gr (P) RN and BlueBullet (L) RN?

Can}t seem to find them online. Thanks.

One place you can try is the JBM website:

I see that they do list some pistol bullets from the major manufactures in the bullet library. You might not be able to find the specific bullets you listed, but should get something close. If you do the trajectory calculation it will give the BC on the output.

Beware that the given BC will be for a G1 shape factor, which has a pointed nose. I don't know what you are going to do with a 9mm 115 FMJ BC, so it might not matter.

Thnx, Laphroaig.

Sorry, I can't help with your question, but I am curious what you are using the ballistic coefficients of 9MM for.

If you were closer to my location I would offer up a session with my Lab Radar. It will measure the velocity drop as the bullet is shot down range.

Load Master, testing bullets for my new CZ, I was interested in the drops of various bullets sighting in at 25 yards.

At 25yds the BC makes pretty much no difference. All the pistol bullets are pretty dismal with how they fly through the air...though I've got a Lyman 147 boat-tail mould that throws about the slipperiest bullet I think you'll find in 9mm. The heavies will normally be subsonic which is where the boat-tail really works the best. Plus you don't have to worry about dropping back through the sonic wall downrange like you will with the lighter bullets.
