I have a 34,46 and 350.I'd like to find a chart or a way to calculate the ballistic coefficients of the pellets I'm using in each gun.I have a crony ,benchrest and 50 yd. range but don't know the formulas or procedure.
Anyone up on this stuff?

This is sort of cheating but here is what you need for a 34 and 350.

Duh, I didn't read what you wrote well enough. You asked for a chart also and I was thinking you just wanted to calculate on your own.

I have the book you are looking for. It contains BCs and trajectory tables for most all pellets, .17 thru .25 Got it from FSI. I believe it is upgradable as new pellets emerge. I would take $20 for it shipped.
