Hello,
I used to do a bunch of ballistics testing back in the day. Getting back into airgunning so hopefully I will get much more data coming up in the near future. Anyways I just wanted to share a little bit of what I have collected previously. I apologize in advance for the difficulty of reading this data, it was hard to format the data into this text box.
Pellet Information:
Manufacture: Predator
Pellet make: Big Boy Senior
Manufacturer Specified Weight: 28.6 [grains]
Actual weight: 28.3 [grains]
Weight Deviation: +/- 0.4 [grains]
Sectional Density: 0.081 [pounds(inch2)-1]
Pellet Length: 0.429 [inches]
Length Deviation: +/- 0.003 [inches]
Airgun Information:
Airgun/model: Airforce Condor
Caliber: .22 caliber
Power Source: high pressure air
Pressure: 2800 [pounds(inch2)-1]
Power Level Number: 6
Test Day Information:
Date of Test: July 29th 2010
Place of Test: Shamokin, Pennsylvania (outdoors)
Temperature: 83 degrees fahrenheit
Barometric Pressure: 29.89 inches of mercury
Altitude: 850 [feet]
Humidity: 63 %
Muzzle velocity: 1000
50.0
velocity: 860.9 
Ballistic Coefficient: 0.052 G1
I think these projectiles have maybe been discontinued? From what I am seeing they look to be rebranded under skenco newboy senior?

I was rather quite unimpressed with the ballistic coefficient of this projectile, although the terminal performance of this projectile did awesome!
Thats all I have for now, until next time! (=
