Pellet ballistic information

[Tims229]

Could anyone tell me if ballistic information is available for pellets? I haven't been able to find any information. Does anyone have this type of information? Or at least know where I could find it.  Thanks!

Edit***I'm referring to ballistic coefficient.

ChairGun has a built in database with lots of BCs.... They are a good starting point, but since BC varies with velocity, and even to some degree with the barrel a pellet is fired from, it is only a guide....

Thank you Bob. I'm mostly just looking for general BC to load into the X site when I get it. Interested to see how accurate it'll be with auto compensation.

Here is some very OLD data I measured myself, you can take it for what it's worth....






If you need similar charts for under 500 fps velocities, I have those as well.... There are SIGNIFICANT differences....

Very much appreciated. It should get me in the ballpark. Much more information than I could find anywhere else. I know the BC changes with velocity, but these are good starting points. Thanks again!

Here are a few more .177 at higher velocity....



Roundball (calculated)....



Some .25 cal....



I also have some data that indicates that the JSB 25.4 gr. Kings have a BC about 0.034-0.037 and the 34 gr. Heavies are about 0.050-0.053.... no velocities given, but would be slower than the above chart for the Kings....

Great stuff Bob, thanks again! Apparently you have put some effort into this. I thank you for sharing and also for what you have contributed to this sport we all love.

Dang!  My wife thinks I am obsessed with my air rifles.
