Title: IS there a pellet BC chart somewhere?
Post by: igolfat8 on January 03, 2019, 11:00:40 AM

Is there a ballistic coefficient chart somewhere that lists most of the common pellets co-efficiencies? I would appreciate if someone could point me in the right direction. It would also be helpful if there were and it was made a "sticky".

Here's one such chart: https://hardairmagazine.com/ballistic-coefficients/ (https://hardairmagazine.com/ballistic-coefficients/)

Here's a link to a spreadsheet I made from that data so it would be handy and easy for me to find:

For a comprehensive list of BC numbers of high-BC pellets in .22 cal, cf.
https://www.gatewaytoairguns.org/GTA/index.php?topic=149053 (https://www.gatewaytoairguns.org/GTA/index.php?topic=149053)


This collection of BCs and other pellet data draws from all over the internet and lists BC data not found on some other popular lists, like:
—JSB Exact Jumbo Beast 33.95gr
—JSB Ultra Shock Heavy 25.39gr
—JSB Straton Jumbo Monster 25.9gr
—H&N Rabbit Magnum Power 25.31gr


Also included is a rebranding-key — i.e., what pellets have been rebranded under a different name.


Of course, once Bob aka rsterne starts playing with a Labradar in a couple of years and assembles variable-velocity BC lists, this will be the end of all fixed-BC lists...!
Go, Bob! We cheer for you!  ;D
