JSB Heavy Ultra Shock .22 ballistic coefficient

[sen]

Hi, guys.
Has anyone measured the BC of the JSB Heavy Ultra Shock .22, 25.39 grains?
I tried searching on the web, went through some pellet BC databases, found nothing for this model...
I know the BC is relative, I only have one chronograph and hence cannot measure it.
Judging by the weight of the pellet and its shape, the BC should be close to 0.03.
I need an approximate estimate, even though made with another gun/barrel at another distance.
Thanks.

You can measure the statistical average of it...

Take the average of several shots at one range and then take the average of several shots at a second range and then use Chairgun to calculate the BC.

Thanks, oldspook. I still need to find another chronograph as mine is a Combro, it is attached to the muzzle of the gun, so it can't be used at another distance
